mkfs.fat

Creates an MS-DOS filesystem inside a partition.

• Create a fat filesystem inside partition 1 on device b (sdb1):

mkfs.fat {{/dev/sdb1}}

• Create filesystem with a volume-name:

mkfs.fat -n {{volume_name}} {{/dev/sdb1}}

• Create filesystem with a volume-id:

mkfs.fat -i {{volume_id}} {{/dev/sdb1}}

• Use 5 instead of 2 file allocation tables:

mkfs.fat -f 5 {{/dev/sdb1}}
