создать файловую систему MS-DOS FAT (create an MS-DOS FAT filesystem)
Описание (Description)
mkfs.fat
is used to create a FAT filesystem on a device or in an
image file. DEVICE is the special file corresponding to the
device (e.g. /dev/sdXX) or the image file (which does not need to
exist when the option -C
is given). BLOCK-COUNT is the number of
blocks on the device and size of one block is always 1024 bytes,
independently of the sector size or the cluster size. Therefore
BLOCK-COUNT specifies size of filesystem in KiB unit and not in
the number of sectors (like for all other mkfs.fat
options). If
omitted, mkfs.fat
automatically chooses a filesystem size to fill
the available space.
Two different variants of the FAT filesystem are supported.
Standard is the FAT12, FAT16 and FAT32 filesystems as defined by
Microsoft and widely used on hard disks and removable media like
USB sticks and SD cards. The other is the legacy Atari variant
used on Atari ST.
In Atari mode, if not directed otherwise by the user, mkfs.fat
will always use 2 sectors per cluster, since GEMDOS doesn't like
other values very much. It will also obey the maximum number of
sectors GEMDOS can handle. Larger filesystems are managed by
raising the logical sector size. An Atari-compatible serial
number for the filesystem is generated, and a 12 bit FAT is used
only for filesystems that have one of the usual floppy sizes
(720k, 1.2M, 1.44M, 2.88M), a 16 bit FAT otherwise. This can be
overridden with the -F
option. Some PC-specific boot sector
fields aren't written, and a boot message (option -m
) is ignored.
