-Announcing the new curses based fdisk program... cfdisk
-
-cfdisk is a curses based disk drive partitioning program that can
-create partitions for a wide variety of operating systems including
-Linux, MS-DOS and OS/2. cfdisk was inspired by the fdisk program, by
-A. V. Le Blanc (LeBlanc@mcc.ac.uk). I hope that this program will be
-useful to both new and old Linux users, and I hope it will make the
-installation process easier.
-
-
- **** WARNING ****
-If you write a bad partition table to disk, it may destroy data and
-partitions.
-
-
-You can FTP cfdisk from ftp.cs.unc.edu in the /pub/martin/linux
-directory.
-
-I would also like comments (good and bad) on the user interface, logic
-and ease of use. If you have any suggestions for improvements, I
-would be happy to hear them.
-
-My e-mail address is martin@cs.unc.edu.

-`fdisk': the Linux partition table editor
-=========================================
-
-`fdisk' is the Linux partition table editor. In this section we
-examine this utility and try to describe it thoroughly enough so that
-anyone can use it.
-
-* Contents:
-
-* Disks and how they are described.
-* Dividing up your disk.
-* The `fdisk' command.
-* Deleting and adding partitions.
-* Active flags and system types.
-* Extra commands for experts.
-* Warnings for `fdisk' users.
-
-
-Disks and how they are described
---------------------------------
-
-A typical disk consists physically of one or more circular objects
-called "platters", which rotate about a central axis. Devices called
-"heads" move to specified places on the disk surface to read or write
-information. There is usually one head on each side of every platter,
-and all these heads are attached to a comb-like controller arm which
-moves all of them at the same time, either closer to the centre of the
-disk, or closer to the outer edge.
-
-Suppose the arm is in one position, putting an area of the disk
-surface within reach of one or another of the heads. This total area,
-everything that is accessible without moving the arm, is called a
-"cylinder". (A cylinder is a barrel-shaped cross section of a disk,
-consisting of a circular strip from each side of each platter.) The
-part of a cylinder that one head can read or write without moving is
-called a "track".
-
-Each track is divided into several pie-shaped slices called
-"sectors", which are the smallest parts of the disk which can be read
-or written at a time. The sectors on one disk are usually all the same
-size.
-
-In fact, there are not always two heads to every platter, there are
-some disks which do not have the same amount of data in every cylinder,
-and there may be disks which do not have the same amount of data in
-every sector. These features are usually hidden on PCs by the
-controller card or the BIOS, which map the physical geometry of a disk
-onto a logical geometry, which is what is actually used to access the
-disk.
-
-The numbers which describe the "geometry" of a disk are
-
- 1. The number of cylinders it contains.
-
- 2. The number of tracks per cylinder, which is the number of heads.
-
- 3. The number of sectors per track.
-
- 4. The number of bytes per sector.
-
-These numbers vary from disk to disk, but a typical PC disk might
-have about 1000 cylinders, half a dozen heads, and 15 or 20 sectors per
-track, with each sector containing 512 bytes or characters; such a disk
-contains 40 to 60 megabytes of data. A "double density" floppy disk
-contains 40 cylinders, with 2 heads (2 tracks per cylinder), and with 9
-sectors per track; such a disk contains 360 kilobytes, or 360 * 1024
-characters. A "high density" 3.5 inch floppy contains 80 cylinders,
-with 2 heads and 18 sectors per track, or 1.44 megabytes, or 1440 *
-1024 characters.
-
-The exact size of a track or cylinder in bytes varies from one disk
-to another. This `fdisk' for Linux deals mainly with cylinders, since
-this is the best unit to use when allocating space for partitions. It
-reports partition sizes in "blocks" of 1024 bytes, or 2 sectors, since
-`mkswap' and the various `mkfs' programs require this number. A block
-is the smallest amount of space which can be set aside for a file in
-the current file systems.
-
-An operating system, such as Linux or DOS or OS/2, may use a disk in
-any way that it wishes, but if two operating systems share the same
-disk, they must agree on who owns what, or else one will interfere with
-the other (that is, by damaging the other's files). A "partition" is a
-section of a hard disk which is handled as a unit by all operating
-systems which can access the disk. The standard way to define
-partitions (for the moment) is the "partition table", a list of
-information which is stored in parts of the disk that don't belong to
-any of the systems using the disk. The beginning of the partition
-table is stored in the disk's primary boot sector, and the rest is
-stored in a chain of sectors scattered throughout the disk.
-
-The first sector on the disk is called the "primary boot block" or
-"primary boot sector" because (1) it comes first, before other, similar
-sectors; (2) it tells where the other, similar sectors are found, so
-that it is logically `prior' to them; and (3) it usually contains code
-which is executed when the system boots up. This sector contains a
-table describing at most four partitions. These areas are called
-"primary partitions".
-
-The partition table in the primary boot sector may also describe at
-most one "extended partition". This is a large area of the disk,
-usually containing all the space which is not in any primary partition.
-Within this space we can set aside other areas which are called
-"logical partitions", because they look almost exactly like primary
-partitions. In fact, the main difference between them is that we can
-boot from primary partitions, while we cannot boot from logical
-partitions. This happens because the address of a primary partition is
-in a fixed place, whereas the address of a secondary partition is not,
-so we require a more complicated process to discover it, one which is
-too difficult for most primary boot programs.
-
-
-Dividing up your disk
----------------------
-
-It is a good idea to plan ahead before you start creating partitions
-on your disk. If you set aside a partition for some purpose, it is not
-easy to change its size: you must backup all the data from the partition,
-whether to floppies, to another partition, to another hard disk, or
-somewhere else; then you must edit the table which describes this
-partition, so changing its size; then you must reboot and initialise
-the new partition, formatting it, for example, under DOS, or running
-`mkfs' under Linux; finally you can copy all the data back. It is
-possible, if you have several partitions, to copy data back and forth
-between them while you change their sizes, but this is a bit risky and
-time consuming. It is better to plan ahead what you will need, since
-it is hard to change it afterwards.
-
-Many people with large disks and recent versions of DOS have their
-entire file system on one large partition. They usually ask, `Isn't
-there any way I can reformat my disk without copying everything off?'
-There is no way to do it using standard DOS utilities, and there is no
-truly safe way to do it using commercial software, because, if you make
-a mistake, you will lose the entire contents of your disk. If you are
-going to back up your disk anyway, you might as well copy the data back
-safely. The Linux FAQ contains references to tools and procedures
-which will allow you to do this, if you dare.
-
-DOS and Linux both allow you to access several partitions on a
-single disk; on DOS these are treated as if they were separate disks or
-drives, and under Linux they are treated as different "devices".
-
-You can have up to 64 partitions on a single IDE disk, or up to 16
-partitions on a single SCSI disk, at least as far as Linux is
-concerned; in practice you will rarely want so many. The maximum size
-of a Linux file system on a single partition depends on the type of
-file system you use. Minix file systems are limited to 64 megabytes.
-You may have all of your Linux files in a single partition, or you may
-have two, three, or more Linux file systems. Similarly you may have
-one or more DOS partitions. If you have several small partitions, you
-run much less risk of losing all your files if your disk gets
-corrupted. On the other hand, you may run out of space on a small
-partition more easily.
-
-Under DOS, you must refer to each partition by a separate drive
-letter, but all partitions are automatically accessible. Under Linux
-only the root partition is automatically accessible, but once we mount
-another partition, it is indistinguishable from the rest of the file
-system. Disks are usually mounted by a command in one of the system
-startup files, `/etc/rc', so you need not worry about having to do it
-yourself whenever you boot the system. But even ordinary users may
-be allowed to mount removable hard disks and floppy disks.
-
-Linux requires at least one partition, which is the `root' of the
-file system. You may prefer to have a separate partition for `/usr',
-which contains most of the executable files, or for `/home', which
-contains most of your private files. You may also wish to set aside a
-partition to use for swap space, depending on the amount of memory your
-PC has. You will certainly need swap space if you have less than 4 Mb
-of RAM and wish to compile anything substantial. You can reserve swap
-space in a file, but you need a partition big enough to hold it, and
-this will probably be less efficient than having a partition devoted to
-swap.
-
-The disk space you need for Linux is discussed in README.prepare.
-
-Are you going to boot Linux from the hard disk, or will you boot
-from a floppy? Some boot programs place severe restrictions on where
-the boot partition can be. LILO is more relaxed about this, but does
-require either the Master Boot Record on your first hard disk, or the
-boot record on one of the first four partitions on your first hard disk.
-
-If you have an extended partition with logical partitions in it, you
-can have only three primary partitions containing data.
-
-
-The `fdisk' command
--------------------
-
-Every operating system, whether DOS, OS/2, or Linux, should provide
-its own utility for editing hard disk partition tables. At least four
-of these utilities have been called `fdisk', for `Fixed DISK setup
-program', where `fixed' means `not removable'. I believe the first PC
-program named `fdisk' came from Microsoft in about 1985; before that
-time disks were too small to divide into separate sections.
-
-Every operating system has its own peculiarities. Normally you
-should set up a partition for the use of one operating system by using
-its own `fdisk' program. Do not use the Linux `fdisk' to create
-partitions for DOS or for any system other than Linux; otherwise you
-may have problems.
-
-An `fdisk' program performs two functions: it reports how the disk is
-configured, and it changes that configuration by adding or deleting
-partitions. Most `fdisk' programs can also change other information in
-partition tables.
-
-This `fdisk' for Linux operates on one hard disk at a time. If you
-give the command
-
- fdisk
-
-it reports on, and is able to change, `/dev/hda', the first hard
-disk. (If you have no `/dev/hda', `fdisk' uses `/dev/sda' as the
-default device.) To look at or change the second hard disk, `/dev/hdb',
-give the command
-
- fdisk /dev/hdb
-
-To look at or change the first SCSI disk, give the command
-
- fdisk /dev/sda
-
-There are some special forms of the `fdisk' command. One of them,
-suggested by Jim Winstead, simply lists all partitions on all available
-disks:
-
- fdisk -l (where `l' is a letter, not the digit `1')
-
-The option `-v' is provided to list the current version of the
-`fdisk' command. Finally, there is an option `-s' which is not really
-intended for interactive use. It causes fdisk to print the size of a
-partition in blocks of 1024 bytes as follows:
-
- fdisk -s /dev/hda7
- 39934
-
-Because this is intended to be used by `mkfs' and `mkswap' programs,
-it does not return the size of extended partitions or of partitions
-whose system type code is less than 10 (hexadecimal a). If you start
-`fdisk' without using one of these special options, it responds by
-asking for a command:
-
- Command (m for help): _
-
-Each `fdisk' command consists of a single letter, which must be
-followed by <RETURN> before it is obeyed. Upper and lower case are not
-distinguished. Anything you type after the first character is ignored.
-Give the command `m', and you should see this menu:
- Command action
- a toggle a bootable flag
- d delete a partition
- l list known partition types
- m print this menu
- n add a new partition
- p print the partition table
- q quit without saving changes
- t change a partition's system id
- u change display/entry units
- v verify the partition table
- w write table to disk and exit
- x extra functionality (experts only)
-
- Command (m for help): _
-
-The simplest commands are Print, Verify, and Quit. On a small disk, the
-Print command might produce a display like this one:
-
- Disk /dev/hda: 5 heads, 17 sectors, 977 cylinders
- Units = cylinders of 85 * 512 bytes
-
- Device Boot Begin Start End Blocks Id System
- /dev/hda1 * 1 1 236 10021+ 1 DOS 12-bit FAT
- /dev/hda2 837 837 977 5992+ 5 Extended
- /dev/hda3 * 237 237 836 25500 83 Linux native
- /dev/hda5 837 837 936 4249+ 82 Linux swap
- /dev/hda6 942 942 977 1522 1 DOS 12-bit FAT
-
-There are 5 partitions reported; `/dev/hda4' does not appear because
-it is not allocated. Partitions 1 and 3 are flagged as bootable. The
-size of each partition is reported in 1 kilobyte blocks; hence the
-primary Linux partition, partition 3, is 25 1/2 megabytes in size. The
-`+' after three of the sizes warns that these partitions contain an odd
-number of sectors: Linux normally allocates filespace in 1 kilobyte
-blocks, so the extra sector in partition 5 is wasted. Id numbers are
-reported in hexadecimal and explained in English.
-
-The display/entry units may be either cylinders or sectors. The
-default is cylinders, but changing the units makes the print command
-display the following table for the system reported above:
-
- Disk /dev/hda: 5 heads, 17 sectors, 977 cylinders
- Units = sectors of 1 * 512 bytes
-
- Device Boot Begin Start End Blocks Id System
- /dev/hda1 * 1 17 20059 10021+ 1 DOS 12-bit FAT
- /dev/hda2 71060 71060 83044 5992+ 5 Extended
- /dev/hda3 * 20060 20060 71059 25500 83 Linux native
- /dev/hda5 71061 71061 79559 4249+ 82 Linux swap
- /dev/hda6 79985 80001 83044 1522 1 DOS 12-bit FAT
-
-The start of data in both DOS partitions is 16 sectors after the
-beginning of the partition: this is one reason why you should use DOS's
-own `FDISK' to create DOS partitions. Changing the units to sectors
-also affects the way in which the new partition command asks for the
-beginning and end of a new partition.
-
-*Warning*: it is dangerous to create a new partition when the
-display/entry units are sectors.
-
-The Verify command is useful because
-
- 1. It warns you if anything is wrong. *Always* do a Verify command
- to check your work before writing any changes to disk.
-
- 2. It reports how many unallocated sectors there are on the disk.
-
-The Quit command is also useful. `fdisk' does not actually change
-any data on your disk unless you give a Write command. If you are
-unhappy about any changes you may have made, give the Quit command, and
-your disk will remain as it was before you ran `fdisk'. You can also
-interrupt `fdisk' with `CTRL-C'.
-
-
-Deleting and adding partitions
-------------------------------
-
-Deleting a partition is simple. Give the Delete command by typing
-`d'. `fdisk' asks:
-
- Partition number (1-6): _
-
-Once you get this far, you must either delete a partition or
-interrupt the program with `CTRL-C' (or whatever your current interrupt
-character is). Note:
-
- 1. You may delete a nonexistent partition. You will get a warning
- message.
-
- 2. You may delete an extended partition. This has the side effect of
- deleting all partitions greater than or equal to 5.
-
- 3. You may delete a logical partition. In that case, all partitions
- above it are renumbered at once. For example, if you delete
- partition 5, then partition 6 becomes known as partition 5, and
- partition 7 as partition 6.
-
-Adding a partition is just a bit more complicated. Give the New
-command by typing `n'. `fdisk' allows you to
-
- 1. Create a primary partition, if there is a free slot in the primary
- partition table.
-
- 2. Create an extended partition if there is a free slot in the
- primary partition table, and if there is no extended partition.
-
- 3. Create a logical partition if an extended partition exists.
-
-If more than one of these actions is possible, you will be asked to
-select Primary, Extended, or Logical, depending on what is currently
-permissible. Before you create a primary or an extended partition, you
-are asked what slot it is to have in the table (1-4).
-
-You may not add a primary or an extended partition if the selected
-slot in the primary partition table is already occupied: in that case
-you simply return to the main menu. You are not allowed to add a new
-primary partition unless there are sectors available outside the
-extended partition. You are not allowed to add a new logical partition
-unless there are sectors available inside the extended partition.
-
-If space is available, you are prompted for the first cylinder:
-
- First sector ([237]-977): _
-
-The limits are the lowest and the highest cylinders in which sectors
-are available in the appropriate part of the disk. The square-bracketed
-number is what you'll get if you simply press enter. Not all numbers in
-this range are necessarily available: they may fall inside an existing
-partition. If you select a cylinder which is already in use, you are
-told off and prompted again for the first cylinder. After selecting the
-first cylinder, you are prompted again:
-
- Last cylinder or +size or +sizeM or +sizeK (237-[836]): _
-
-The limits are the cylinder you have chosen as the first cylinder,
-and the highest cylinder which contains a legitimate upper boundary for
-the new partition. The square-bracketed number is what you'll get if
-you simply press enter. In other words, all numbers in the given range are
-legitimate, unlike those in the first range of cylinders. You may also
-specify the size of a partition in megabytes, kilobytes, or in the
-current units (cylinders or sectors). A plus sign `+' indicates that
-your answer is a size rather than a boundary, and the suffix `m' or `k'
-(upper or lower case) indicates that the size is not given in units of
-sectors or cyliners, but in megabytes or kilobytes respectively. Thus
-possible answers to the last cylinder request above are
-
-700
- Make cylinder 700 the last cylinder in the partition.
-
-+300
- Make cylinder 237 + 300 = 537 the last cylinder in the partition.
-
-+15m
- Make the partition at least 15 megabytes in size.
-
-+12500k
- Make the partition at least 12,500 kilobytes in size.
-
-If you specify a size which is too large or an end which is out of
-range, fdisk complains and repeats the prompt.
-
-Adding or deleting partitions has no effect unless you subsequently
-give the Write command. Please remember to give the Verify command
-first, just before giving the Write command: this is a safety
-precaution. After giving the Write command, you will see this message:
-
- The partition table has been altered!
- Calling ioctl() to re-read partition table.
- Syncing disks.
-
-If there are no further messages, the kernel has successfully copied
-the information from the partition table into its own internal table.
-But sometimes you will see a message like this one:
-
- Re-read table failed with error 16: Device or resource busy.
- Reboot your system to ensure the partition table is updated.
-
-In this case, depending on what you have changed in the partition
-table, it may be dangerous to continue working without rebooting,
-since you may lose or corrupt your data.
-
-
-Here are some important things to note:
-
- 1. Before you reboot, you *may* run `fdisk' again, either to manage
- another disk, or to make additional changes to the same disk, or
- just to check that the changes have been made as you expected.
- This is true even after you receive the message warning you to
- reboot.
-
- 2. It is not a good idea to run any of the programs `mkfs', `mkswap',
- `mount', or `swapon' if you have received the warning message but
- have not rebooted. In this case it is dangerous to run any program,
- but these in particular may cause serious damage to the data on your
- disk, including the partition tables themselves.
-
-
-Active flags and system types
------------------------------
-
-The active flag is a bit in the partition table entry which marks a
-partition as bootable. This is important to some primary boot sector
-programs, which will not boot from an unflagged partition. Other such
-programs do not allow more than one partition to be flagged. Some,
-like LILO, ignore the flags completely. I prefer to flag all bootable
-partitions as active so that they stand out on the menu which `fdisk'
-lists. Fdisk prints a star after the name of a partition's device file
-if its active flag is set.
-
-The Active command changes, or toggles, a partition's active flag.
-Give the Active command, and select a partition by number. If it was
-marked inactive, it will be flagged as active; if it was flagged as
-active, it will be marked inactive. You may set the active flag on an
-extended or logical partition, though the meaning of such a flag is by
-no means clear. This can be used to install LILO as a secondary boot
-loader to boot a Linux which lives on a second hard disk.
-
-The Type command changes the ID number which describes what type a
-partition is. `fdisk' currently recognises 30 system IDs, in the sense
-that it prints a string for each of them, but it allows you to change
-any system ID to any other, with the following exceptions: you may not
-change any partition to or from the type Extended, and you may not
-change a partition whose type is Empty (0) to any other type. You may,
-however, change the type of any data partition to 0, which is
-equivalent to deleting it.
-
-The new system ID or type code is a hexadecimal number. There are
-two ways of listing the numbers which `fdisk' recognises: use the List
-command, which prints the list, or use the Type command, which, when it
-prompts you for the code, says
-
- Hex code (type L to list codes): _
-
-where the upper case `L' is used for clarity. The codes printed are:
-Some of these numbers are a trifle uncertain. By default `fdisk' uses
-a type of 83. It used to use 81, the type code used by the MINIX
-`fdisk'. It seemed prudent to change the default since (a) many Linux
-`minix' file systems are no longer compatible with MINIX, (b) the ext2
-file system, a native Linux file system, is fairly stable, as is the
-Xia file system, and (c) the number 81 causes problems with DR-DOS.
-Linux does not usually care what values you use for type codes, but
-other systems, in particular DOS, OS/2, and DR-DOS, may.
-
-The value of 82 for Linux swap partitions is my own invention, and
-is intended to give some recognisable distinction to the partitions
-when the values are displayed in hexadecimal.
-
-New active flags and new system type codes are not written to the
-disk until you exit from `fdisk' with the Write command, as described
-above, in the section on deleting and adding partitions.
-
-
-Extra commands for experts
---------------------------
-
-The eXtra command `x' puts `fdisk' into `expert' mode, in which a
-slightly different set of commands is available. The Active, Delete,
-List, New, Type, Verify, and `eXpert' commands are not available in
-expert mode. The commands Write and Quit are available as in ordinary
-mode, the Print command is available, but produces output in a slightly
-different format, and of course the Menu command prints the expert
-menu. There are several new commands.
-
- 1. The Return command brings you back to the main menu.
-
- 2. The Extended command prints the list of table entries which point
- to other tables. Ordinary users do not need this information.
- The data is shown as it is stored. The same format is used for
- the expert Print command.
-
- 3. The dangerous Begin command allows you to move the start of data
- in a partition away from its beginning. Other systems create
- partitions with this format, and it is sometimes useful to be able
- to reproduce it.
-
- 4. The slightly dangerous Cylinders command allows you to change the
- available number of cylinders. For SCSI disk owners, note that we
- require not the actual number of physical cylinders, but the
- number of logical cylinders used by DOS and other operating
- systems.
-
- 5. The extremely dangerous Heads and Sectors commands allow you to
- change the number of heads and sectors. It should not be
- necessary to use these commands unless you have a SCSI disk, whose
- geometry Linux is not always able to determine. SCSI disk owners
- note that we need not the actual number of heads or of sectors per
- track, but the number believed to exist by DOS and other operating
- systems. *Warning*: If you set either of these numbers to a bad
- value, you may lose all data on your disk.
-
-Always, after giving any of the commands Begin, Cylinder, Heads, or
-Sectors, you should Return to the main menu and give the Verify command.
-
-
-Warnings for `fdisk' users
---------------------------
-
-In general, you should not use this `fdisk' program to create
-partitions for other operating systems, only for Linux. Nor should you
-use `fdisk' commands from other operating systems to create partitions
-for Linux.
-
-DR-DOS 5.0 and 6.0 are reported to have difficulties with partition
-ID codes of 80 or more. The Linux `fdisk' used to set the system type
-of new partitions to hexadecimal 81. DR-DOS seems to confuse this with
-hexadecimal 1, a DOS code. The values 82 for swap and 83 for file
-systems should not cause problems with DR-DOS. If they do, you may use
-the `fdisk' command `t' to change the system code of any Linux
-partitions to some number less than hexadecimal 80; I suggest 42 and 43
-for the moment.
-
-Partitioning a hard disk may destroy data which is on that disk if you
-are not careful. Go slowly, write down a description of the partition
-tables before you changed them, and always verify before you write.
-
-Most operating systems and utilities expect that all partitions begin and
-end at cylinder boundaries. This version of `fdisk' does so by default,
-but you can use it to create partitions which begin or end anywhere.
-This does not normally affect Linux, but it is very dangerous, as other
-operating systems (including DOS) may try to `correct' the partition
-boundaries.
-
-It is dangerous to create a new partition when the display/entry
-units are sectors.
-
-The Verify command warns you if anything is wrong. *Always* give a
-Verify command before writing any changes to disk.
-
-If you set the disk geometry (tracks per cylinder, or sectors per
-track) to an incorrect value, you may lose all data on your disk.

-.TH CFDISK 8 "3 June 1995" "The BOGUS Linux Release" "Linux Programmer's Manual"
-.SH NAME
-cfdisk \- Curses based disk partition table manipulator for Linux
-.SH SYNOPSIS
-.BI "cfdisk [ \-avz ] [ \-c " cylinders " ] [ \-h " heads " ]"
-.BI "[ \-s " sectors-per-track " ] [ -P " opt " ] [ " device " ]"
-.SH DESCRIPTION
-.B cfdisk
-is a curses based program for partitioning a hard disk drive. The
-.I device
-can be any one of the following:
-.sp
-.nf
-.RS
-/dev/hda [default]
-/dev/hdb
-/dev/sda
-/dev/sdb
-/dev/sdc
-/dev/sdd
-.RE
-.fi
-
-.B cfdisk
-first tries to read the geometry of the hard disk. If it fails, an
-error message is displayed and
-.B cfdisk
-exits. This should only happen when partitioning a SCSI drive on an
-adapter without a BIOS. To correct this problem, you can set the
-.IR cylinders ", " heads " and " sectors-per-track
-on the command line. Next,
-.B cfdisk
-tries to read the current partition table from the disk drive. If it
-is unable to figure out the partition table, an error is displayed and
-the program will exit. This might also be caused by incorrect
-geometry information, and can be overridden on the command line.
-Another way around this problem is with the
-.B \-z
-option. This will ignore the partition table on the disk.
-
-The main display is composed of four sections, from top to bottom: the
-header, the partitions, the command line and a warning line. The
-header contains the program name and version number followed by the
-disk drive and its geometry. The partitions section always displays
-the current partition table. The command line is the place where
-commands and text are entered. The available commands are usually
-displayed in brackets. The warning line is usually empty except when
-there is important information to be displayed. The current partition
-is highlighted with reverse video (or an arrow if the
-.B \-a
-option is given). All partition specific commands apply to the
-current partition.
-
-The format of the partition table in the partitions section is, from
-left to right: Name, Flags, Partition Type, Filesystem Type and Size.
-The name is the partition device name. The flags can be
-.IR Boot ,
-which designates a bootable partition or
-.IR NC ,
-which stands for "Not Compatible with DOS or OS/2". DOS, OS/2 and
-possibly other operating systems require the first sector of the first
-partition on the disk and all logical partitions to begin on the
-second head. This wastes the second through the last sector of the
-first track of the first head (the first sector is taken by the
-partition table itself).
-.B cfdisk
-allows you to recover these "lost" sectors with the maximize command
-.RB ( m ).
-.I Note:
-.BR fdisk (8)
-and some early versions of DOS create all partitions with the number
-of sectors already maximized. For more information, see the maximize
-command below. The partition type can be one of
-.IR Primary " or " Logical .
-For unallocated space on the drive, the partition type can also be
-.IR Pri/Log ,
-or empty (if the space is unusable). The filesystem type section
-displays the name of the filesystem used on the partition, if known.
-If it is unknown, then
-.I Unknown
-and the hex value of the filesystem type are displayed. A special
-case occurs when there are sections of the disk drive that cannot be
-used (because all of the primary partitions are used). When this is
-detected, the filesystem type is displayed as
-.IR Unusable .
-The size field displays the size of the partition in megabytes (by
-default). It can also display the size in sectors and cylinders (see
-the change units command below). If an asterisks
-.RB ( * )
-appears after the size, this means that the partition is not aligned
-on cylinder boundaries.
-.SH "DOS 6.x WARNING"
-
-The DOS 6.x FORMAT command looks for some information in the first
-sector of the data area of the partition, and treats this information
-as more reliable than the information in the partition table. DOS
-FORMAT expects DOS FDISK to clear the first 512 bytes of the data area
-of a partition whenever a size change occurs. DOS FORMAT will look at
-this extra information even if the /U flag is given -- we consider
-this a bug in DOS FORMAT and DOS FDISK.
-
-The bottom line is that if you use cfdisk or fdisk to change the size of a
-DOS partition table entry, then you must also use
-.B dd
-to zero the first 512 bytes of that partition before using DOS FORMAT to
-format the partition. For example, if you were using cfdisk to make a DOS
-partition table entry for /dev/hda1, then (after exiting fdisk or cfdisk
-and rebooting Linux so that the partition table information is valid) you
-would use the command "dd if=/dev/zero of=/dev/hda1 bs=512 count=1" to zero
-the first 512 bytes of the partition. Note:
-
-.B BE EXTREMELY CAREFUL
-if you use the
-.B dd
-command, since a small typo can make all of the data on your disk useless.
-
-For best results, you should always use an OS-specific partition table
-program. For example, you should make DOS partitions with the DOS FDISK
-program and Linux partitions with the Linux fdisk or Linux cfdisk program.
-
-.SH COMMANDS
-.B cfdisk
-commands can be entered by pressing the desired key (pressing
-.I Enter
-after the command is not necessary). Here is a list of the available
-commands:
-.TP
-.B b
-Toggle bootable flag of the current partition. This allows you to
-select which primary partition is bootable on the drive.
-.TP
-.B d
-Delete the current partition. This will convert the current partition
-into free space and merge it with any free space immediately
-surrounding the current partition. A partition already marked as free
-space or marked as unusable cannot be deleted.
-.TP
-.B g
-Change the disk geometry (cylinders, heads, or sectors-per-track).
-.B WARNING:
-This option should only be used by people who know what they are
-doing. A command line option is also available to change the disk
-geometry. While at the change disk geometry command line, you can
-choose to change cylinders
-.RB ( c ),
-heads
-.RB ( h ),
-and sectors per track
-.RB ( s ).
-The default value will be printed at the prompt which you can accept
-by simply pressing the
-.I Enter
-key, or you can exit without changes by pressing the
-.I ESC
-key. If you want to change the default value, simply enter the
-desired value and press
-.IR Enter .
-The altered disk parameter values do not take effect until you return
-the main menu (by pressing
-.IR Enter " or " ESC
-at the change disk geometry command line. If you change the geometry
-such that the disk appears larger, the extra sectors are added at the
-end of the disk as free space. If the disk appears smaller, the
-partitions that are beyond the new last sector are deleted and the
-last partition on the drive (or the free space at the end of the
-drive) is made to end at the new last sector.
-.TP
-.B h
-Print the help screen.
-.TP
-.B m
-Maximize disk usage of the current partition. This command will
-recover the the unused space between the partition table and the
-beginning of the partition, but at the cost of making the partition
-incompatible with DOS, OS/2 and possibly other operating systems.
-This option will toggle between maximal disk usage and DOS, OS/2,
-etc. compatible disk usage. The default when creating a partition is
-to create DOS, OS/2, etc. compatible partitions.
-.TP
-.B n
-Create new partition from free space. If the partition type is
-.IR Primary " or " Logical ,
-a partition of that type will be created, but if the partition type is
-.IR Pri/Log ,
-you will be prompted for the type you want to create. Be aware that
-(1) there are only four slots available for primary partitions and (2)
-since there can be only one extended partition, which contains all of
-the logical drives, all of the logical drives must be contiguous (with
-no intervening primary partition).
-.B cfdisk
-next prompts you for the size of the partition you want to create.
-The default size, equal to the entire free space of the current
-partition, is display in megabytes. You can either press the
-.I Enter
-key to accept the default size or enter a different size at the
-prompt.
-.B cfdisk
-accepts size entries in megabytes
-.RB ( M )
-[default], kilobytes
-.RB ( K ),
-cylinders
-.RB ( C )
-and sectors
-.RB ( S )
-by entering the number immediately followed by one of
-.RB ( M ", " K ", " C " or " S ).
-If the partition fills the free space available, the partition is
-created and you are returned to the main command line. Otherwise, the
-partition can be created at the beginning or the end of the free
-space, and
-.B cfdisk
-will ask you to choose where to place the partition. After the
-partition is created,
-.B cfdisk
-automatically adjusts the other partition's partition types if all of
-the primary partitions are used.
-.TP
-.B p
-Print the partition table to the screen or to a file. There are
-several different formats for the partition that you can choose from:
-.sp
-.RS
-.TP
-.B r
-Raw data format (exactly what would be written to disk)
-.TP
-.B s
-Partition table in sector order format
-.TP
-.B t
-Partition table in raw format
-.RE
-
-.RS
-The
-.I raw data format
-will print the sectors that would be written to disk if a
-.BR w rite
-command is selected. First, the primary partition table is printed,
-followed by the partition tables associated with each logical
-partition. The data is printed in hex byte by byte with 16 bytes per
-line.
-
-The
-.I partition table in sector order format
-will print the partition table ordered by sector number. The fields,
-from left to right, are the number of the partition, the partition
-type, the first sector, the last sector, the offset from the first
-sector of the partition to the start of the data, the length of the
-partition, the filesystem type (with the hex value in parenthesis),
-and the flags (with the hex value in parenthesis). In addition to the
-primary and logical partitions, free and unusable space is printed and
-the extended partition is printed before the first logical partition.
-
-If a partition does not start or end on a cylinder boundary or if the
-partition length is not divisible by the cylinder size, an asterisks
-.RB ( * )
-is printed after the non-aligned sector number/count. This usually
-indicates that a partition was created by an operating system that
-either does not align partitions to cylinder boundaries or that used
-different disk geometry information. If you know the disk geometry of
-the other operating system, you could enter the geometry information
-with the change geometry command
-.RB ( g ).
-
-For the first partition on the disk and for all logical partitions, if
-the offset from the beginning of the partition is not equal to the
-number of sectors per track (i.e., the data does not start on the
-first head), a number sign
-.RB ( # )
-is printed after the offset. For the remaining partitions, if the
-offset is not zero, a number sign will be printed after the offset.
-This corresponds to the
-.I NC
-flag in the partitions section of the main display.
-
-The
-.I partition table in raw format
-will print the partition table ordered by partition number. It will
-leave out all free and unusable space. The fields, from left to
-right, are the number of the partition, the flags (in hex), the
-starting head, sector and cylinder, the filesystem ID (in hex), the
-ending head, sector and cylinder, the starting sector in the partition
-and the number of sectors in the partition. The information in this
-table can be directly translated to the
-.IR "raw data format" .
-
-The partition table entries only have 10 bits available to represent
-the starting and ending cylinders. Thus, when the absolute starting
-(ending) sector number is on a cylinder greater than 1023, the maximal
-values for starting (ending) head, sector and cylinder are printed.
-This is the method used by OS/2, and thus fixes the problems
-associated with OS/2's fdisk rewriting the partition table when it is
-not in this format. Since Linux and OS/2 use absolute sector counts,
-the values in the starting and ending head, sector and cylinder are
-not used.
-.RE
-.TP
-.B q
-Quit program. This will exit the program without writing any data to
-disk.
-.TP
-.B t
-Change the filesystem type. By default, new partitions are created as
-.I Linux
-partitions, but since
-.B cfdisk
-can create partitions for other operating systems, change partition
-type allows you to enter the hex value of the filesystem you desire.
-A list of the know filesystem types is displayed. You can type in the
-filesystem type at the prompt or accept the default filesystem type
-.RI [ Linux ].
-.TP
-.B u
-Change units of the partition size display. It will rotate through
-megabytes, sectors and cylinders.
-.TP
-.B W
-Write partition table to disk (must enter an upper case W). Since
-this might destroy data on the disk, you must either confirm or deny
-the write by entering `yes' or `no'. If you enter `yes',
-.B cfdisk
-will write the partition table to disk and the tell the kernel to
-re-read the partition table from the disk. The re-reading of the
-partition table works is most cases, but I have seen it fail. Don't
-panic. It will be correct after you reboot the system. In all cases,
-I still recommend rebooting the system--just to be safe.
-.TP
-.I Up Arrow
-.TP
-.I Down Arrow
-Move cursor to the previous or next partition. If there are more
-partitions than can be displayed on a screen, you can display the next
-(previous) set of partitions by moving down (up) at the last (first)
-partition displayed on the screen.
-.TP
-.I CTRL-L
-Redraws the screen. In case something goes wrong and you cannot read
-anything, you can refresh the screen from the main command line.
-.TP
-.B ?
-Print the help screen.
-
-.RE
-All of the commands can be entered with either upper or lower case
-letters (except for
-.BR W rites).
-When in a sub-menu or at a prompt to enter a filename, you can hit the
-.I ESC
-key to return to the main command line.
-.SH OPTIONS
-.TP
-.B \-a
-Use an arrow cursor instead of reverse video for highlighting the
-current partition.
-.TP
-.B \-v
-Print the version number and copyright.
-.TP
-.B \-z
-Start with zeroed partition table. This option is useful when you
-want to repartition your entire disk.
-.I Note:
-this option does not zero the partition table on the disk; rather, it
-simply starts the program without reading the existing partition
-table.
-.TP
-.BI \-c " cylinders"
-.TP
-.BI \-h " heads"
-.TP
-.BI \-s " sectors-per-track"
-Override the number of cylinders, heads and sectors per track read
-from the BIOS. If your BIOS or adapter does not supply this
-information or if it supplies incorrect information, use these options
-to set the disk geometry values.
-.TP
-.BI \-P " opt"
-Prints the partition table in specified formats.
-.I opt
-can be one or more of "r", "s" or "t". See the
-.BR p rint
-command (above) for more information on the print formats.

-.TH CFDISK 8 "25 April 1994" "The BOGUS Linux Release" "Linux Programmer's Manual"
-.SH NAME
-cfdisk \- Curses based disk partition table manipulator for Linux
-.SH SYNOPSIS
-.BI "cfdisk [ \-avz ] [ \-c " cylinders " ] [ \-h " heads " ]"
-.BI "[ \-s " sectors-per-track " ] [ -P " opt " ] [ " device " ]"
-.SH DESCRIPTION
-.B cfdisk
-is a curses based program for partitioning a hard disk drive. The
-.I device
-can be any one of the following:
-.sp
-.nf
-.RS
-/dev/hda [default]
-/dev/hdb
-/dev/sda
-/dev/sdb
-/dev/sdc
-/dev/sdd
-.RE
-.fi
-
-.B cfdisk
-first tries to read the geometry of the hard disk. If it fails, an
-error message is displayed and
-.B cfdisk
-exits. This should only happen when partitioning a SCSI drive on an
-adapter without a BIOS. To correct this problem, you can set the
-.IR cylinders ", " heads " and " sectors-per-track
-on the command line. Next,
-.B cfdisk
-tries to read the current partition table from the disk drive. If it
-is unable to figure out the partition table, an error is displayed and
-the program will exit. This might also be caused by incorrect
-geometry information, and can be overridden on the command line.
-Another way around this problem is with the
-.B \-z
-option. This will ignore the partition table on the disk.
-
-The main display is composed of four sections, from top to bottom: the
-header, the partitions, the command line and a warning line. The
-header contains the program name and version number followed by the
-disk drive and its geometry. The partitions section always displays
-the current partition table. The command line is the place where
-commands and text are entered. The available commands are usually
-displayed in brackets. The warning line is usually empty except when
-there is important information to be displayed. The current partition
-is highlighted with reverse video (or an arrow if the
-.B \-a
-option is given). All partition specific commands apply to the
-current partition.
-
-The format of the partition table in the partitions section is, from
-left to right: Name, Flags, Partition Type, Filesystem Type and Size.
-The name is the partition device name. The flags can be
-.IR Boot ,
-which designates a bootable partition or
-.IR NC ,
-which stands for "Not Compatible with DOS or OS/2". DOS, OS/2 and
-possibly other operating systems require the first sector of the first
-partition on the disk and all logical partitions to begin on the
-second head. This wastes the second through the last sector of the
-first track of the first head (the first sector is taken by the
-partition table itself).
-.B cfdisk
-allows you to recover these "lost" sectors with the maximize command
-.RB ( m ).
-.I Note:
-.BR fdisk (8)
-and some early versions of DOS create all partitions with the number
-of sectors already maximized. For more information, see the maximize
-command below. The partition type can be one of
-.IR Primary " or " Logical .
-For unallocated space on the drive, the partition type can also be
-.IR Pri/Log ,
-or empty (if the space is unusable). The filesystem type section
-displays the name of the filesystem used on the partition, if known.
-If it is unknown, then
-.I Unknown
-and the hex value of the filesystem type are displayed. A special
-case occurs when there are sections of the disk drive that cannot be
-used (because all of the primary partitions are used). When this is
-detected, the filesystem type is displayed as
-.IR Unusable .
-The size field displays the size of the partition in megabytes (by
-default). It can also display the size in sectors and cylinders (see
-the change units command below). If an asterisks
-.RB ( * )
-appears after the size, this means that the partition is not aligned
-on cylinder boundaries.
-.SH "DOS 6.x WARNING"
-
-The DOS 6.x FORMAT command looks for some information in the first
-sector of the data area of the partition, and treats this information
-as more reliable than the information in the partition table. DOS
-FORMAT expects DOS FDISK to clear the first 512 bytes of the data area
-of a partition whenever a size change occurs. DOS FORMAT will look at
-this extra information even if the /U flag is given -- we consider
-this a bug in DOS FORMAT and DOS FDISK.
-
-The bottom line is that if you use cfdisk or fdisk to change the size of a
-DOS partition table entry, then you must also use
-.B dd
-to zero the first 512 bytes of that partition before using DOS FORMAT to
-format the partition. For example, if you were using cfdisk to make a DOS
-partition table entry for /dev/hda1, then (after exiting fdisk or cfdisk
-and rebooting Linux so that the partition table information is valid) you
-would use the command "dd if=/dev/zero of=/dev/hda1 bs=512 count=1" to zero
-the first 512 bytes of the partition.
-.B BE EXTREMELY CAREFUL
-if you use the
-.B dd
-command, since a small typo can make all of the data on your disk useless.
-
-.B BE EXTREMELY CAREFUL
-if you use the
-.B dd
-command, since a small typo can make all of the data on your disk useless.
-
-For best resutls, you should always use an OS-specific partition table
-program. For example, you should make DOS partitions with the DOS FDISK
-program and Linux partitions with the Linux fdisk or Linux cfdisk program.
-
-.SH COMMANDS
-.B cfdisk
-commands can be entered by pressing the desired key (pressing
-.I Enter
-after the command is not necessary). Here is a list of the available
-commands:
-.TP
-.B b
-Toggle bootable flag of the current partition. This allows you to
-select which primary partition is bootable on the drive.
-.TP
-.B d
-Delete the current partition. This will convert the current partition
-into free space and merge it with any free space immediately
-surrounding the current partition. A partition already marked as free
-space or marked as unusable cannot be deleted.
-.TP
-.B g
-Change the disk geometry (cylinders, heads, or sectors-per-track).
-.B WARNING:
-This option should only be used by people who know what they are
-doing. A command line option is also available to change the disk
-geometry. While at the change disk geometry command line, you can
-choose to change cylinders
-.RB ( c ),
-heads
-.RB ( h ),
-and sectors per track
-.RB ( s ).
-The default value will be printed at the prompt which you can accept
-by simply pressing the
-.I Enter
-key, or you can exit without changes by pressing the
-.I ESC
-key. If you want to change the default value, simply enter the
-desired value and press
-.IR Enter .
-The altered disk parameter values do not take effect until you return
-the main menu (by pressing
-.IR Enter " or " ESC
-at the change disk geometry command line. If you change the geometry
-such that the disk appears larger, the extra sectors are added at the
-end of the disk as free space. If the disk appears smaller, the
-partitions that are beyond the new last sector are deleted and the
-last partition on the drive (or the free space at the end of the
-drive) is made to end at the new last sector.
-.TP
-.B h
-Print the help screen.
-.TP
-.B m
-Maximize disk usage of the current partition. This command will
-recover the the unused space between the partition table and the
-beginning of the partition, but at the cost of making the partition
-incompatible with DOS, OS/2 and possibly other operating systems.
-This option will toggle between maximal disk usage and DOS, OS/2,
-etc. compatible disk usage. The default when creating a partition is
-to create DOS, OS/2, etc. compatible partitions.
-.TP
-.B n
-Create new partition from free space. If the partition type is
-.IR Primary " or " Logical ,
-a partition of that type will be created, but if the partition type is
-.IR Pri/Log ,
-you will be prompted for the type you want to create. Be aware that
-(1) there are only four slots available for primary partitions and (2)
-since there can be only one extended partition, which contains all of
-the logical drives, all of the logical drives must be contiguous (with
-no intervening primary partition).
-.B cfdisk
-next prompts you for the size of the partition you want to create.
-The default size, equal to the entire free space of the current
-partition, is display in megabytes. You can either press the
-.I Enter
-key to accept the default size or enter a different size at the
-prompt.
-.B cfdisk
-accepts size entries in megabytes
-.RB ( M )
-[default], kilobytes
-.RB ( K ),
-cylinders
-.RB ( C )
-and sectors
-.RB ( S )
-by entering the number immediately followed by one of
-.RB ( M ", " K ", " C " or " S ).
-If the partition fills the free space available, the partition is
-created and you are returned to the main command line. Otherwise, the
-partition can be created at the beginning or the end of the free
-space, and
-.B cfdisk
-will ask you to choose where to place the partition. After the
-partition is created,
-.B cfdisk
-automatically adjusts the other partition's partition types if all of
-the primary partitions are used.
-.TP
-.B p
-Print the partition table to the screen or to a file. There are
-several different formats for the partition that you can choose from:
-.sp
-.RS
-.TP
-.B r
-Raw data format (exactly what would be written to disk)
-.TP
-.B s
-Partition table in sector order format
-.TP
-.B t
-Partition table in raw format
-.RE
-
-.RS
-The
-.I raw data format
-will print the sectors that would be written to disk if a
-.BR w rite
-command is selected. First, the primary partition table is printed,
-followed by the partition tables associated with each logical
-partition. The data is printed in hex byte by byte with 16 bytes per
-line.
-
-The
-.I partition table in sector order format
-will print the partition table ordered by sector number. The fields,
-from left to right, are the number of the partition, the partition
-type, the first sector, the last sector, the offset from the first
-sector of the partition to the start of the data, the length of the
-partition, the filesystem type (with the hex value in parenthesis),
-and the flags (with the hex value in parenthesis). In addition to the
-primary and logical partitions, free and unusable space is printed and
-the extended partition is printed before the first logical partition.
-
-If a partition does not start or end on a cylinder boundary or if the
-partition length is not divisible by the cylinder size, an asterisks
-.RB ( * )
-is printed after the non-aligned sector number/count. This usually
-indicates that a partition was created by an operating system that
-either does not align partitions to cylinder boundaries or that used
-different disk geometry information. If you know the disk geometry of
-the other operating system, you could enter the geometry information
-with the change geometry command
-.RB ( g ).
-
-For the first partition on the disk and for all logical partitions, if
-the offset from the beginning of the partition is not equal to the
-number of sectors per track (i.e., the data does not start on the
-first head), a number sign
-.RB ( # )
-is printed after the offset. For the remaining partitions, if the
-offset is not zero, a number sign will be printed after the offset.
-This corresponds to the
-.I NC
-flag in the partitions section of the main display.
-
-The
-.I partition table in raw format
-will print the partition table ordered by partition number. It will
-leave out all free and unusable space. The fields, from left to
-right, are the number of the partition, the flags (in hex), the
-starting head, sector and cylinder, the filesystem ID (in hex), the
-ending head, sector and cylinder, the starting sector in the partition
-and the number of sectors in the partition. The information in this
-table can be directly translated to the
-.IR "raw data format" .
-
-The partition table entries only have 10 bits available to represent
-the starting and ending cylinders. Thus, when the absolute starting
-(ending) sector number is on a cylinder greater than 1023, the maximal
-values for starting (ending) head, sector and cylinder are printed.
-This is the method used by OS/2, and thus fixes the problems
-associated with OS/2's fdisk rewriting the partition table when it is
-not in this format. Since Linux and OS/2 use absolute sector counts,
-the values in the starting and ending head, sector and cylinder are
-not used.
-.RE
-.TP
-.B q
-Quit program. This will exit the program without writing any data to
-disk.
-.TP
-.B t
-Change the filesystem type. By default, new partitions are created as
-.I Linux
-partitions, but since
-.B cfdisk
-can create partitions for other operating systems, change partition
-type allows you to enter the hex value of the filesystem you desire.
-A list of the know filesystem types is displayed. You can type in the
-filesystem type at the prompt or accept the default filesystem type
-.RI [ Linux ].
-.TP
-.B u
-Change units of the partition size display. It will rotate through
-megabytes, sectors and cylinders.
-.TP
-.B W
-Write partition table to disk (must enter an upper case W). Since
-this might destroy data on the disk, you must either confirm or deny
-the write by entering `yes' or `no'. If you enter `yes',
-.B cfdisk
-will write the partition table to disk and the tell the kernel to
-re-read the partition table from the disk. The re-reading of the
-partition table works is most cases, but I have seen it fail. Don't
-panic. It will be correct after you reboot the system. In all cases,
-I still recommend rebooting the system--just to be safe.
-.TP
-.I Up Arrow
-.TP
-.I Down Arrow
-Move cursor to the previous or next partition. If there are more
-partitions than can be displayed on a screen, you can display the next
-(previous) set of partitions by moving down (up) at the last (first)
-partition displayed on the screen.
-.TP
-.I CTRL-L
-Redraws the screen. In case something goes wrong and you cannot read
-anything, you can refresh the screen from the main command line.
-.TP
-.B ?
-Print the help screen.
-
-.RE
-All of the commands can be entered with either upper or lower case
-letters (except for
-.BR W rites).
-When in a sub-menu or at a prompt to enter a filename, you can hit the
-.I ESC
-key to return to the main command line.
-.SH OPTIONS
-.TP
-.B \-a
-Use an arrow cursor instead of reverse video for highlighting the
-current partition.
-.TP
-.B \-v
-Print the version number and copyright.
-.TP
-.B \-z
-Start with zeroed partition table. This option is useful when you
-want to repartition your entire disk.
-.I Note:
-this option does not zero the partition table on the disk; rather, it
-simply starts the program without reading the existing partition
-table.
-.TP
-.BI \-c " cylinders"
-.TP
-.BI \-h " heads"
-.TP
-.BI \-s " sectors-per-track"
-Override the number of cylinders, heads and sectors per track read
-from the BIOS. If your BIOS or adapter does not supply this
-information or if it supplies incorrect information, use these options
-to set the disk geometry values.
-.TP
-.BI \-P " opt"
-Prints the partition table in specified formats.
-.I opt
-can be one or more of "r", "s" or "t". See the
-.BR p rint
-command (above) for more information on the print formats.
-.SH "SEE ALSO"
-fdisk(8)
-.SH BUGS
-The current version does not support multiple disks (future addition).

-.TH FDISK 8 "11 June 1998" "Linux 2.0" "Linux Programmer's Manual"
-.SH NAME
-fdisk \- Partition table manipulator for Linux
-.SH SYNOPSIS
-.BI "fdisk [\-b] [\-u] [" device ]
-.sp
-.BI "fdisk \-l [\-b] [\-u] [" "device ..." ]
-.sp
-.BI "fdisk \-s " "partition ..."
-.sp
-.BI "fdisk \-v
-.SH DESCRIPTION
-Hard disks can be divided into one or more logical disks called
-.IR partitions .
-This division is described in the
-.I "partition table"
-found in sector 0 of the disk.
-
-In the BSD world one talks about `disk slices' and a `disklabel'.
-
-Linux needs at least one partition, namely for its root file system.
-It can use swap files and/or swap partitions, but the latter are more
-efficient. So, usually one will want a second Linux partition
-dedicated as swap partition.
-On Intel compatible hardware, the BIOS that boots the system
-can often only access the first 1024 cylinders of the disk.
-For this reason people with large disks often create a third partition,
-just a few MB large, typically mounted on
-.IR /boot ,
-to store the kernel image and a few auxiliary files needed at boot time,
-so as to make sure that this stuff is accessible to the BIOS.
-There may be reasons of security, ease of administration and backup,
-or testing, to use more than the minimum number of partitions.
-
-.B fdisk
-(in the first form of invocation)
-is a menu driven program for creation and manipulation of
-partition tables.
-It understands DOS type partition tables and BSD or SUN type disklabels.
-
-The
-.I device
-is usually one of the following:
-.br
-.nf
-.RS
-/dev/hda
-/dev/hdb
-/dev/sda
-/dev/sdb
-.RE
-.fi
-(/dev/hd[a-h] for IDE disks, /dev/sd[a-p] for SCSI disks,
-/dev/ed[a-d] for ESDI disks, /dev/xd[ab] for XT disks).
-A device name refers to the entire disk.
-
-The
-.I partition
-is a
-.I device
-name followed by a partition number. For example,
-.B /dev/hda1
-is the first partition on the first IDE hard disk in the system.
-IDE disks can have up to 63 partitions, SCSI disks up to 15.
-See also
-.IR /usr/src/linux/Documentation/devices.txt .
-
-A BSD/SUN type disklabel can describe 8 partitions,
-the third of which should be a `whole disk' partition.
-Do not start a partition that actually uses its first sector
-(like a swap partition) at cylinder 0, since that will
-destroy the disklabel.
-
-A DOS type partition table can describe an unlimited number
-of partitions. In sector 0 there is room for the description
-of 4 partitions (called `primary'). One of these may be an
-extended partition; this is a box holding logical partitions,
-with descriptors found in a linked list of sectors, each
-preceding the corresponding logical partitions.
-The four primary partitions, present or not, get numbers 1-4.
-Logical partitions start numbering from 5.
-
-In a DOS type partition table the starting offset and the size
-of each partition is stored in two ways: as an absolute number
-of sectors (given in 32 bits) and as a Cylinders/Heads/Sectors
-triple (given in 10+8+6 bits). The former is OK - with 512-byte
-sectors this will work up to 2 TB. The latter has two different
-problems. First of all, these C/H/S fields can be filled only
-when the number of heads and the number of sectors per track
-are known. Secondly, even if we know what these numbers should be,
-the 24 bits that are available do not suffice.
-DOS uses C/H/S only, Windows uses both, Linux never uses C/H/S.
-
-If possible,
-.B fdisk
-will obtain the disk geometry automatically. This is not
-necessarily the physical disk geometry (indeed, modern disks do not
-really have anything like a physical geometry, certainly not something
-that can be described in simplistic Cylinders/Heads/Sectors form),
-but is the disk geometry that MS-DOS uses for the partition table.
-
-Usually all goes well by default, and there are no problems if
-Linux is the only system on the disk. However, if the disk has
-to be shared with other operating systems, it is often a good idea
-to let an fdisk from another operating system make at least one
-partition. When Linux boots it looks at the partition table, and
-tries to deduce what (fake) geometry is required for good
-cooperation with other systems.
-
-Whenever a partition table is printed out, a consistency check is performed
-on the partition table entries. This check verifies that the physical and
-logical start and end points are identical, and that the partition starts
-and ends on a cylinder boundary (except for the first partition).
-
-Some versions of MS-DOS create a first partition which does not begin
-on a cylinder boundary, but on sector 2 of the first cylinder.
-Partitions beginning in cylinder 1 cannot begin on a cylinder boundary, but
-this is unlikely to cause difficulty unless you have OS/2 on your machine.
-
-A sync() and a BLKRRPART ioctl() (reread partition table from disk)
-are performed before exiting when the partition table has been updated.
-Long ago it used to be necessary to reboot after the use of fdisk.
-I do not think this is the case anymore - indeed, rebooting too quickly
-might cause loss of not-yet-written data. Note that both the kernel
-and the disk hardware may buffer data.
-
-.SH "DOS 6.x WARNING"
-
-The DOS 6.x FORMAT command looks for some information in the first
-sector of the data area of the partition, and treats this information
-as more reliable than the information in the partition table. DOS
-FORMAT expects DOS FDISK to clear the first 512 bytes of the data area
-of a partition whenever a size change occurs. DOS FORMAT will look at
-this extra information even if the /U flag is given -- we consider
-this a bug in DOS FORMAT and DOS FDISK.
-
-The bottom line is that if you use cfdisk or fdisk to change the size of a
-DOS partition table entry, then you must also use
-.B dd
-to zero the first 512 bytes of that partition before using DOS FORMAT to
-format the partition. For example, if you were using cfdisk to make a DOS
-partition table entry for /dev/hda1, then (after exiting fdisk or cfdisk
-and rebooting Linux so that the partition table information is valid) you
-would use the command "dd if=/dev/zero of=/dev/hda1 bs=512 count=1" to zero
-the first 512 bytes of the partition.
-
-.B BE EXTREMELY CAREFUL
-if you use the
-.B dd
-command, since a small typo can make all of the data on your disk useless.
-
-For best results, you should always use an OS-specific partition table
-program. For example, you should make DOS partitions with the DOS FDISK
-program and Linux partitions with the Linux fdisk or Linux cfdisk program.
-
-.SH OPTIONS
-.TP
-.B \-v
-Print version number of
-.B fdisk
-program and exit.
-.TP
-.B \-l
-List the partition tables for
-.BR /dev/hd[a-d] ,
-.BR /dev/sd[a-h] ,
-.BR /dev/ed[a-d] ,
-and then exit.
-.TP
-.B \-b
-When listing partition tables, also output a `Begin' column,
-as earlier versions of fdisk did by default.
-(Note: the values in this column, when given in cylinder units,
-cannot be larger than 1023. There is nothing wrong if Begin and Start
-differ, at least not as far as Linux is concerned.)
-.TP
-.B \-u
-When listing partition tables, give sizes in sectors instead
-of cylinders.
-.TP
-.BI "\-s " partition
-The
-.I size
-of the partition (in blocks) is printed on the standard output.
-This value is normally used as an argument to the
-.BR mkfs (8)
-program to specify the size of the partition which will be formatted.
-(Older versions of fdisk would do this only if the partition id is
-greater than 10, in an attempt to refuse DOS partitions;
-this test has been deleted.)
-Note that
-.B "sfdisk -s"
-gives different (namely, correct) answers.
-Reasons for the difference are that the kernel and
-.B fdisk
-need not have the same idea about partition numbering
-(e.g., in case you have BSD slices), and have different
-ideas about the size of an extended partition.
-.SH BUGS
-There are several *fdisk programs around.
-Each has its problems and strengths.
-Try them in the order
-.BR cfdisk ,
-.BR fdisk ,
-.BR sfdisk .

- * Before Linux version 0.95c, this program requires a kernel patch.
- *
- * Modified, Tue Feb 2 18:46:49 1993, faith@cs.unc.edu to better support SCSI.
- * Modified, Sat Feb 27 18:11:27 1993, faith@cs.unc.edu: added extfs support.
- * Modified, Sat Mar 6 10:14:12 1993, faith@cs.unc.edu: added more comments.
- * Modified, Sat Mar 6 12:25:45 1993, faith@cs.unc.edu:
- * Added patches from Michael Bischoff (i1041905@ws.rz.tu-bs.de
- * or mbi@mo.math.nat.tu-bs.de) to fix the following problems:
- * 1) Incorrect mapping of head/sector/cylinder to absolute sector
- * 2) Odd sector count causes one sector to be lost
- * Modified, Sat Mar 6 12:25:52 1993, faith@cs.unc.edu: improved verification.
- * Modified, Sat Apr 17 15:00:00 1993, LeBlanc@mcc.ac.uk: add -s, fix -l.
- * Modified, Sat Apr 24 10:00:00 1993, LeBlanc@mcc.ac.uk: fix overlap bug.
- * Modified, Wed May 5 21:30:00 1993, LeBlanc@mcc.ac.uk: errors to stderr.
- * Modified, Mon Mar 21 20:00:00 1994, LeBlanc@mcc.ac.uk:
- * more stderr for messages, avoid division by 0, and
- * give reboot message only if ioctl(fd, BLKRRPART) fails.
- * Modified, Mon Apr 25 01:01:05 1994, martin@cs.unc.edu:
- * 1) Added support for DOS, OS/2, ... compatibility. We should be able
- * use this fdisk to partition our drives for other operating systems.
- * 2) Added a print the raw data in the partition table command.
- * Modified, Wed Jun 22 21:05:30 1994, faith@cs.unc.edu:
- * Added/changed a few partition type names to conform to cfdisk.
- * (suggested by Sujal, smpatel@wam.umd.edu)
- * Modified 3/5/95 leisner@sdsp.mc.xerox.com -- on -l only open
- * devices RDONLY (instead of RDWR). This allows you to
- * have the disks as rw-r----- with group disk (and if you
- * want is safe to setguid fdisk to disk).
- * Modified Sat Mar 11 10:02 1995 with more partition types, faith@cs.unc.edu
- * Modified, Thu May 4 01:11:45 1995, esr@snark.thyrsus.com:
- * It's user-interface cleanup time.
- * Actual error messages for out-of-bounds values (what a concept!).
- * Enable read-only access to partition table for learners.
- * Smart defaults for most numeric prompts.

-.TH FRAG 8 "8 January 1994" "Linux 0.99" "Linux Programmer's Manual"
-.SH NAME
-frag \- simple fragmentation checker
-.SH SYNOPSIS
-.B /usr/sbin/frag
-.B "[ \-s [ \-s ]]"
-filename ...
-.SH DESCRIPTION
-.B frag
-will report the file system fragmentation on a specified
-.IR filename .
-If the
-.I filename
-is a directory,
-.B frag
-will recursively descend the directory.
-.SH OPTIONS
-.TP
-.B \-s
-Silent (may be set to 1 or 2). The first
-.B \-s
-eliminates the file by file statistics, and just prints the
-examined directories and a summary. The second
-.B \-s
-eliminates the printing of the directories, and just prints a
-summary. This option is useful when
-.B frag
-is used on a directory.
-.SH "SEE ALSO"
-.BR mkfs (8),
-.BR fsck (8),
-.BR mkefs (8),
-.BR efsck (8)
-.SH BUGS
-.B frag
-will get caught in an infinite loop in the /proc filesystem.
-.SH AUTHORS

.SH NAME
mkswap \- set up a Linux swap area
.SH SYNOPSIS
-.B "mkswap [ \-c ]"
-.IB device " [" size-in-blocks "]"
+.BI "mkswap [\-c] [\-v" N "] [\-f] " device " [" size "]"
.SH DESCRIPTION
.B mkswap
sets up a Linux swap area on a device or in a file.
+(After creating the swap area, you need the
+.B swapon
+command to start using it. Usually swap areas are listed in
+.I /etc/fstab
+so that they can be taken into use at boot time by a
+.B swapon -a
+command in some boot script.)
+
The
.I device
-is usually of the following form:
-
-.nf
-.RS
-/dev/hda[1-8]
-/dev/hdb[1-8]
-/dev/sda[1-8]
-/dev/sdb[1-8]
-.RE
-.fi
+argument will usually be a disk partition (something like
+.I /dev/hda4
+or
+.IR /dev/sdb7 )
+but can also be a file.
+The Linux kernel does not look at partition Id's, but
+many installation scripts will assume that partitions
+of hex type 82 (LINUX_SWAP) are meant to be swap partitions.
The
-.I size-in-blocks
-parameter is the desired size of the file system, in blocks. This
-information is determined automatically by
+.I size
+parameter is superfluous but retained for backwards compatibility.
+(It specifies the desired size of the swap area in 1024-byte blocks.
.B mkswap
-if it is omitted. Block counts are rounded down so that the total
-size is an integer multiple of the machine's page size. Only block
-counts in the range MINCOUNT..MAXCOUNT are allowed. If the block count
-exceeds the MAXCOUNT, it is truncated to that value and a warning
-message is issued.
+will use the entire partition or file if it is omitted.)
-The MINCOUNT and MAXCOUNT values for a swap area are:
+Linux knows about two styles of swap areas, old style and new style.
+The last 10 bytes of the first page of the swap area distinguishes
+them: old style has `SWAP_SPACE', new style has `SWAPSPACE2' as
+signature.
-.RS
-MINCOUNT = 10 * PAGE_SIZE / 1024
-.br
-MAXCOUNT = (PAGE_SIZE - 10) * 8 * PAGE_SIZE / 1024
-.RE
+In the old style, the rest of this first page was a bit map,
+with a 1 bit for each usable page of the swap area.
+Since the first page holds this bit map, the first bit is 0.
+Also, the last 10 bytes hold the signature. So, if the page
+size is S, an old style swap area can describe at most
+8*(S-10)-1 pages used for swapping.
+With S=4096 (as on i386), the useful area is at most 133890048 bytes
+(almost 128 MB if you believe in 1 MB=2^20 bytes), and the rest is wasted.
+On an alpha and sparc64, with S=8192, the useful area is at most
+535560992 bytes (almost 512 MB with the same proviso).
-For example, on a machine with 4kB pages (e.g., x86), we get:
+The old setup wastes most of this bitmap page, because zero bits
+denote bad blocks or blocks past the end of the swap space,
+and a simple integer suffices to indicate the size of the swap space,
+while the bad blocks, if any, can simply be listed. Nobody wants
+to use a swap space with hundreds of bad blocks. (I would not even
+use a swap space with 1 bad block.)
+In the new style swap area this is precisely what is done.
+The maximum useful size of a swap area is now (2^31 - 2*S) bytes,
+roughly 2 GB.
-.RS
-MINCOUNT = 10 * 4096 / 1024 = 40
-.br
-MAXCOUNT = (4096 - 10) * 8 * 4096 / 1024 = 130752
-.RE
+Note that before 2.1.117 the kernel allocated one byte for each page,
+while it now allocates two bytes, so that taking a swap area of 2 GB
+in use might require 2 MB of kernel memory.
-As each block is 1kB large, the swap area in this example could have a
-size that is anywhere in the range from 40kB up to 127.6875MB.
+Presently, Linux allows 8 swap areas. The areas in use can be seen
+in the file
+.I /proc/swaps
+(since 2.1.25).
-If you don't know the page size that your machine uses, you may be
-able to look it up with "cat /proc/cpuinfo".
+.B mkswap
+refuses areas smaller than 10 pages.
-The reason for the limit on MAXCOUNT is that a single page is used to
-hold the swap bitmap at the start of the swap area, where each bit
-represents a single page. The reason for the -10, is that the
-signature is "SWAP-SPACE" -- 10 characters.
+If you don't know the page size that your machine uses, you may be
+able to look it up with "cat /proc/cpuinfo" (or you may not -
+the contents of this file depend on architecture and kernel version).
To setup a swap file, it is necessary to create that file before
running
-.B mkswap .
-A sequence of commands similar to the following is reasonable for this
-purpose:
+.B mkswap ,
+e.g. using a command like
.nf
.RS
-# dd if=/dev/zero of=swapfile bs=1024 count=8192
-# mkswap swapfile 8192
-# sync
-# swapon swapfile

.SH OPTIONS
.TP
.B \-c
-Check the device for bad blocks before creating the file system. If any
-are found, the count is printed. This option is meant to be used for swap
-partitions
-.BR only ,
-and should
-.B not
-be used for regular files! To make sure that regular files do not contain
-bad blocks, the partition that contains the regular file should have been
-created with
-.BR "mkfs -c" .
+Check the device (if it is a block device) for bad blocks
+before creating the swap area.
+If any are found, the count is printed.
+.TP
+.B \-f
+On SPARC, force creation of the swap area.
+Without this option
+.B mkswap
+will refuse to create a v0 swap on a device with a valid SPARC superblock,
+as that probably means one is going to erase the partition table.
+.TP
+.B \-v0
+Create an old style swap area.
+.TP
+.B \-v1
+Create a new style swap area.
+
+.LP
+If no \-v option is given,
+.B mkswap
+will default to old style if the size of the swap area does not
+exceed the maximum size of an old style swap area, and also if
+the current kernel is older than 2.1.117 (and also if PAGE_SIZE
+is less than 2048).
+The new style header does not touch the first block, so may be
+preferable (also if the swap area is small), in case you have
+a boot loader or disk label there.

-.TH SFDISK 8 "1 September 1995" "Linux 1.3.23" "Linux Programmer's Manual"
-.SH NAME
-sfdisk \- Partition table manipulator for Linux
-.SH SYNOPSIS
-.BR sfdisk " [options] device"
-.br
-.BR "sfdisk \-s " [partition]
-.SH DESCRIPTION
-.B sfdisk
-has four (main) uses: list the size of a partition, list the partitions
-on a device, check the partitions on a device, and - very dangerous -
-repartition a device.
-
-.SS "List Sizes"
-.BI "sfdisk \-s " partition
-gives the size of
-.I partition
-in blocks. This may be useful in connection with programs like
-.B mkswap
-or so. Here
-.I partition
-is usually something like
-.I /dev/hda1
-or
-.IR /dev/sdb12 ,
-but may also be an entire disk, like
-.IR /dev/xda .
-.br
-.RS
-.nf
-.if t .ft CW
-% sfdisk \-s /dev/hda9
-81599
-%
-.if t .ft R
-.fi
-.RE
-If the partition argument is omitted,
-.B sfdisk
-will list the sizes of all disks, and the total:
-.br
-.RS
-.nf
-.if t .ft CW
-% sfdisk \-s
-/dev/hda: 208896
-/dev/hdb: 1025136
-/dev/hdc: 1031063
-/dev/sda: 8877895
-/dev/sdb: 1758927
-total: 12901917 blocks
-%
-.if t .ft R
-.fi
-.RE
-
-.SS "List Partitions"
-The second type of invocation:
-.BI "sfdisk \-l " "[options] device"
-will list the partitions on this device.
-If the device argument is omitted, the partitions on all hard disks
-are listed.
-.br
-.nf
-.if t .ft CW
-% sfdisk \-l /dev/hdc
-
-Disk /dev/hdc: 16 heads, 63 sectors, 2045 cylinders
-Units = cylinders of 516096 bytes, blocks of 1024 bytes, counting from 0
-
- Device Boot Start End #cyls #blocks Id System
-/dev/hdc1 0+ 406 407\- 205096+ 83 Linux native
-/dev/hdc2 407 813 407 205128 83 Linux native
-/dev/hdc3 814 2044 1231 620424 83 Linux native
-/dev/hdc4 0 \- 0 0 0 Empty
-%
-.if t .ft R
-.fi
-The trailing \- and + signs indicate that rounding has taken place,
-and that the actual value is slightly less (more).
-To see the exact values, ask for a listing with sectors as unit.
-
-.SS "Check partitions"
-The third type of invocation:
-.BI "sfdisk \-V " device
-will apply various consistency checks to the partition tables on
-.IR device .
-It prints `OK' or complains. The \-V option can be used together
-with \-l. In a shell script one might use
-.BI "sfdisk \-V \-q " device
-which only returns a status.
-
-.SS "Create partitions"
-The fourth type of invocation:
-.BI "sfdisk " device
-will cause
-.B sfdisk
-to read the specification for the desired partitioning of
-.I device
-from its standard input, and then to change the partition tables
-on that disk. Thus, it is possible to use
-.B sfdisk
-from a shell script. When
-.B sfdisk
-determines that its standard input is a terminal, it will be
-conversational; otherwise it will abort on any error.
-.LP
-BE EXTREMELY CAREFUL - ONE TYPING MISTAKE AND ALL YOUR DATA IS LOST
-.LP
-As a precaution, one can save the sectors changed by
-.BR sfdisk :
-.RS
-.nf
-.if t .ft CW
-% sfdisk /dev/hdd \-O hdd-partition-sectors.save
-%
-.if t .ft R
-.fi
-.RE
-.LP
-Then, if you discover that you did something stupid before anything
-else has been written to disk, it may be possible to recover
-the old situation with
-.RS
-.nf
-.if t .ft CW
-% sfdisk /dev/hdd \-I hdd-partition-sectors.save
-%
-.if t .ft R
-.fi
-.RE
-
-There are many options.
-
-.SH OPTIONS
-.TP
-.BR \-v " or " \-\-version
-Print version number of
-.B sfdisk
-and exit immediately.
-.TP
-.BR \-? " or " \-\-help
-Print a usage message and exit immediately.
-.TP
-.BR \-T " or " \-\-list-types
-Print the recognized types (system Id's).
-.TP
-.BR \-s " or " \-\-show\-size
-List the size of a partition.
-.TP
-.BR \-g " or " \-\-show\-geometry
-List the kernel's idea of the geometry of the indicated disk(s).
-.TP
-.BR \-l " or " \-\-list
-List the partitions of a device.
-.TP
-.BR \-d
-Dump the partitions of a device in a format useful as input
-to sfdisk. For example,
-.br
-.nf
-.if t .ft CW
- % sfdisk -d /dev/hda > hda.out
- % sfdisk /dev/hda < hda.out
-.if t .ft R
-.fi
-will correct the bad last extended partition that the OS/2
-fdisk creates.
-.TP
-.BR \-V " or " \-\-verify
-Test whether partitions seem correct. (See above.)
-.TP
-.BR \-i " or " \-\-increment
-Number cylinders etc. starting from 1 instead of 0.
-.TP
-.BI \-N " number"
-Change only the single partition indicated. For example:
-.br
-.nf
-.if t .ft CW
- % sfdisk /dev/hdb \-N5
- ,,,*
- %
-.if t .ft R
-.fi
-will make the fifth partition on /dev/hdb bootable (`active')
-and change nothing else. (Probably this fifth partition
-is called /dev/hdb5, but you are free to call it something else,
-like `/my_equipment/disks/2/5' or so).
-.TP
-.BI \-A " number"
-Make the indicated partition(s) active, and all others inactive.
-.TP
-.BI \-c " or " \-\-id " number [Id]"
-If no Id argument given: print the partition Id of the indicated
-partition. If an Id argument is present: change the type (Id) of
-the indicated partition to the given value.
-This option has the two very long forms \-\-print\-id and \-\-change\-id.
-For example:
-.br
-.nf
-.if t .ft CW
- % sfdisk --print-id /dev/hdb 5
- 6
- % sfdisk --change-id /dev/hdb 5 83
- OK
-.if t .ft R
-.fi
-first reports that /dev/hdb5 has Id 6, and then changes that into 83.
-.TP
-.BR \-uS " or " \-uB " or " \-uC " or " \-uM
-Accept or report in units of sectors (blocks, cylinders, megabytes,
-respectively). The default is cylinders, at least when the geometry
-is known.
-.TP
-.BR \-x " or " \-\-show\-extended
-Also list non-primary extended partitions on output,
-and expect descriptors for them on input.
-.TP
-.BI \-C " cylinders"
-Specify the number of cylinders, possibly overriding what the kernel thinks.
-.TP
-.BI \-H " heads"
-Specify the number of heads, possibly overriding what the kernel thinks.
-.TP
-.BI \-S " sectors"
-Specify the number of sectors, possibly overriding what the kernel thinks.
-.TP
-.BR \-f " or " \-\-force
-Do what I say, even if it is stupid.
-.TP
-.BR \-q " or " \-\-quiet
-Suppress warning messages.
-.TP
-.BR \-L " or " \-\-Linux
-Do not complain about things irrelevant for Linux.
-.TP
-.BR \-D " or " \-\-DOS
-For DOS-compatibility: waste a little space.
-(More precisely: if a partition cannot contain sector 0,
-e.g. because that is the MBR of the device, or contains
-the partition table of an extended partition, then
-.B sfdisk
-would make it start the next sector. However, when this
-option is given it skips to the start of the next track,
-wasting for example 33 sectors (in case of 34 sectors/track),
-just like certain versions of DOS do.)
-Certain Disk Managers and boot loaders (such as OSBS, but not
-LILO or the OS/2 Boot Manager) also live in this empty space,
-so maybe you want this option if you use one.
-.TP
-.BR \-\-IBM " or " \-\-leave\-last
-Certain IBM diagnostic programs assume that they can use the
-last cylinder on a disk for disk-testing purposes. If you think
-you might ever run such programs, use this option to tell
-.B sfdisk
-that it should not allocate the last cylinder.
-Sometimes the last cylinder contains a bad sector table.
-.TP
-.B \-n
-Go through all the motions, but do not actually write to disk.
-.TP
-.B \-R
-Only execute the BLKRRPART ioctl (to make the kernel re-read
-the partition table). This can be useful for checking in advance
-that the final BLKRRPART will be successful, and also when you
-changed the partition table `by hand' (e.g., using dd from a backup).
-If the kernel complains (`device busy for revalidation (usage = 2)')
-then something still uses the device, and you still have to unmount
-some file system, or say swapoff to some swap partition.
-.TP
-.B \-\-no\-reread
-When starting a repartitioning of a disk, sfdisk checks that this disk
-is not mounted, or in use as a swap device, and refuses to continue
-if it is. This option suppresses the test. (On the other hand, the \-f
-option would force sfdisk to continue even when this test fails.)
-.TP
-.BI \-O " file"
-Just before writing the new partition, output the sectors
-that are going to be overwritten to
-.I file
-(where hopefully
-.I file
-resides on another disk, or on a floppy).
-.TP
-.BI \-I " file"
-After destroying your filesystems with an unfortunate
-.B sfdisk
-command, you would have been able to restore the old situation
-if only you had preserved it using the \-O flag.
-
-.SH THEORY
-Block 0 of a disk (the Master Boot Record) contains among
-other things four partition descriptors. The partitions
-described here are called
-.I primary
-partitions.
-.LP
-A partition descriptor has 6 fields:
-.br
-.nf
-.RS
-struct partition {
- unsigned char bootable; /* 0 or 0x80 */
- hsc begin_hsc;
- unsigned char id;
- hsc end_hsc;
- unsigned int starting_sector;
- unsigned int nr_of_sectors;
-}
-.RE
-.fi
-.LP
-The two hsc fields indicate head, sector and cylinder of the
-begin and the end of the partition. Since each hsc field only
-takes 3 bytes, only 24 bits are available, which does not
-suffice for big disks (say > 8GB). In fact, due to the wasteful
-representation (that uses a byte for the number of heads, which
-is typically 16), problems already start with 0.5GB.
-However Linux does not use these fields, and problems can arise
-only at boot time, before Linux has been started. For more
-details, see the
-.B lilo
-documentation.
-.LP
-Each partition has a type, its `Id', and if this type is 5
-.IR "" "(`" "extended partition" "')"
-the starting sector of the partition
-again contains 4 partition descriptors. MSDOS only uses the
-first two of these: the first one an actual data partition,
-and the second one again an extended partition (or empty).
-In this way one gets a chain of extended partitions.
-Other operating systems have slightly different conventions.
-Linux also accepts type 85 as equivalent to 5 - this can be
-useful if one wants to have extended partitions under Linux past
-the 1024 cylinder boundary, without DOS FDISK hanging.
-(If there is no good reason, you should just use 5, which is
-understood by other systems.)
-.LP
-Partitions that are not primary or extended are called
-.IR logical .
-Often, one cannot boot from logical partitions (because the
-process of finding them is more involved than just looking
-at the MBR).
-Note that of an extended partition only the Id and the start
-are used. There are various conventions about what to write
-in the other fields. One should not try to use extended partitions
-for data storage or swap.
-
-.SH "INPUT FORMAT"
-.B sfdisk
-reads lines of the form
-.br
-.RS
-<start> <size> <id> <bootable> <c,h,s> <c,h,s>
-.RE
-where each line fills one partition descriptor.
-.LP
-Fields are separated by whitespace, or comma or semicolon possibly
-followed by whitespace; initial and trailing whitespace is ignored.
-Numbers can be octal, decimal or hexadecimal, decimal is default.
-When a field is absent or empty, a default value is used.
-.LP
-The <c,h,s> parts can (and probably should) be omitted -
-.B sfdisk
-computes them from <start> and <size> and the disk geometry
-as given by the kernel or specified using the \-H, \-S, \-C flags.
-.LP
-Bootable is specified as [*|\-], with as default not-bootable.
-(The value of this field is irrelevant for Linux - when Linux
-runs it has been booted already - but might play a role for
-certain boot loaders and for other operating systems.
-For example, when there are several primary DOS partitions,
-DOS assigns C: to the first among these that is bootable.)
-.LP
-Id is given in hex, without the 0x prefix, or is [E|S|L|X], where
-L (LINUX_NATIVE (83)) is the default, S is LINUX_SWAP (82), E
-is EXTENDED_PARTITION (5), and X is LINUX_EXTENDED (85).
-.LP
-The default value of start is the first nonassigned sector/cylinder/...
-.LP
-The default value of size is as much as possible (until next
-partition or end-of-disk).
-.LP
-However, for the four partitions inside an extended partition,
-the defaults are: Linux partition, Extended partition, Empty, Empty.
-.LP
-But when the \-N option (change a single partition only) is given,
-the default for each field is its previous value.
-
-.SH EXAMPLE
-The command
-.RS
-.nf
-.if t .ft CW
-sfdisk /dev/hdc << EOF
-0,407
-,407
-;
-;
-EOF
-.if t .ft R
-.fi
-.RE
-will partition /dev/hdc just as indicated above.
-
-With the \-x option, the number of input lines must be a multiple of 4:
-you have to list the two empty partitions that you never want
-using two blank lines. Without the \-x option, you give one line
-for the partitions inside a extended partition, instead of four,
-and terminate with end-of-file (^D).
-(And
-.B sfdisk
-will assume that your input line represents the first of four,
-that the second one is extended, and the 3rd and 4th are empty.)
-
-.SH "DOS 6.x WARNING"
-
-The DOS 6.x FORMAT command looks for some information in the first
-sector of the data area of the partition, and treats this information
-as more reliable than the information in the partition table. DOS
-FORMAT expects DOS FDISK to clear the first 512 bytes of the data area
-of a partition whenever a size change occurs. DOS FORMAT will look at
-this extra information even if the /U flag is given -- we consider
-this a bug in DOS FORMAT and DOS FDISK.
-.LP
-The bottom line is that if you use sfdisk to change the size of a
-DOS partition table entry, then you must also use
-.B dd
-to zero the first 512 bytes of that partition before using DOS FORMAT to
-format the partition. For example, if you were using sfdisk to make a DOS
-partition table entry for /dev/hda1, then (after exiting sfdisk and
-rebooting Linux so that the partition table information is valid) you
-would use the command "dd if=/dev/zero of=/dev/hda1 bs=512 count=1" to zero
-the first 512 bytes of the partition.
-.B BE EXTREMELY CAREFUL
-if you use the
-.B dd
-command, since a small typo can make all of the data on your disk useless.
-
-For best results, you should always use an OS-specific partition table
-program. For example, you should make DOS partitions with the DOS FDISK
-program and Linux partitions with the Linux sfdisk program.
-
-.SH "DRDOS WARNINGS"
-
-Stephen Tweedie reported (930515): `Most reports of superblock
-corruption turn out to be due to bad partitioning, with one filesystem
-overrunning the start of the next and corrupting its superblock.
-I have even had this problem with the supposedly-reliable DRDOS. This
-was quite possibly due to DRDOS-6.0's FDISK command. Unless I created
-a blank track or cylinder between the DRDOS partition and the
-immediately following one, DRDOS would happily stamp all over the
-start of the next partition. Mind you, as long as I keep a little
-free disk space after any DRDOS partition, I don't have any other
-problems with the two coexisting on the one drive.'
-
-A. V. Le Blanc writes in README.esfdisk: `Dr. DOS 5.0 and 6.0 has been
-reported to have problems cooperating with Linux, and with this version
-of efdisk in particular. This efdisk sets the system type
-to hexadecimal 81. Dr. DOS seems to confuse
-this with hexadecimal 1, a DOS code. If you use Dr. DOS, use the
-efdisk command 't' to change the system code of any Linux partitions
-to some number less than hexadecimal 80; I suggest 41 and 42 for
-the moment.'
-
-A. V. Le Blanc writes in his README.fdisk: `DR-DOS 5.0 and 6.0
-are reported to have difficulties with partition ID codes of 80 or more.
-The Linux `fdisk' used to set the system type
-of new partitions to hexadecimal 81. DR-DOS seems to confuse this with
-hexadecimal 1, a DOS code. The values 82 for swap and 83 for file
-systems should not cause problems with DR-DOS. If they do, you may use
-the `fdisk' command `t' to change the system code of any Linux
-partitions to some number less than hexadecimal 80; I suggest 42 and 43
-for the moment.'
-
-In fact, it seems that only 4 bits are significant for the DRDOS FDISK,
-so that for example 11 and 21 are listed as DOS 2.0. However, DRDOS
-itself seems to use the full byte. I have not been able to reproduce
-any corruption with DRDOS or its fdisk.
-
-.SH BUGS
-A corresponding interactive
-.B cfdisk
-(with curses interface) is still lacking.
-.LP
-There are too many options.

-Examples of the use of sfdisk 3.0 (to partition a disk)
-Input lines have fields <start>,<size>,<type>... - see sfdisk.8.
-Usually no <start> is given, and input lines start with a comma.
-
-Before doing anything with a disk, make sure it is not in use;
-unmount all its file systems, and say swapoff to its swap partitions.
-(The final BLKRRPART ioctl will fail if anything else still uses
-the disk, and you will have to reboot. It is easier to first make
-sure that nothing uses the disk, e.g., by testing:
- % umount /dev/sdb1
- % sfdisk -R /dev/sdb
- BLKRRPART: Device or resource busy
- * Device busy for revalidation (usage=2)
- % swapoff /dev/sdb3
- % sfdisk -R /dev/sdb
- * sdb: sdb1 < sdb5 sdb6 > sdb3
- %
-Note that the starred messages are kernel messages, that may be
-logged somewhere, or written to some other console.
-In sfdisk 3.01 sfdisk automatically does this check, unless told not to.)
-
-1. One big partition:
- sfdisk /dev/hda << EOF
- ;
- EOF
-
-(If there was garbage on the disk before, you may get error messages
-like: `ERROR: sector 0 does not have an msdos signature'
-and `/dev/hda: unrecognized partition'. This does not matter
-if you write an entirely fresh partition table anyway.)

-
-
-4. Preserving the sectors changed by sfdisk.
- % sfdisk -O save-hdd-partition-sectors /dev/hda
- ...
- will write the sectors overwritten by sfdisk to file.
- If you notice that you trashed some partition, you may
- be able to restore things by
- % sfdisk -I save-hdd-partition-sectors /dev/hda
- %
-
-5. Preserving some old partitions.
- % sfdisk -N2 /dev/hda
- ...
- will only change the partition /dev/hda2, and leave the rest
- unchanged. The most obvious application is to change an Id:
- % sfdisk -N7 /dev/hda

-6. Deleting a partition.
-At first I thought of having an option -X# for deleting partitions,
-but there are several ways in which a partition can be deleted, and
-it is probably better to handle this just as a general change.
- % sfdisk -d /dev/hda > ohda
-will write the current tables on the file `ohda'.
------------------------------------------------------------------------
-% cat ohda
-# partition table of /dev/hda

-/dev/hda1 : start= 1, size= 40799, Id= 5
-/dev/hda2 : start= 40800, size= 40800, Id=83

------------------------------------------------------------------------
-In order to delete the partition on /dev/hda3, edit this file
-and feed the result to sfdisk again.

-This is a good way of making changes: dump the current status
-to file, edit the file, and feed it to sfdisk.
-Preserving the file on some other disk could be useful:
-if ever the MBR gets thrashed it can be used to restore
-the old situation.
