fdisk: read topology info from libblkid
and print ('p' command) info about logical and physical sectors and
alignment_offset.
minimum_io_size
we don't use physical sector size directly, because on RAIDs is
better to use minimum_io_size (aka stripe chunk size). For disk drives
is minimum_io_size the same value as physical sector size.
alignment_offset
For compatibility with legacy operating systems some vendors provide
disks where logical and physical sectors are aligned at sector 63
(= geometry.sectors). In other words the physical 4KB sectors
start at LBA -1. Then the physical boundary is at:
alignment_offset + N * phy_sector_size
