# 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}}`
