fdformat – Low-level formats a floppy disk
fdformat [ -n ] device
fdformat does a low level format on a floppy disk. device is usually one of the following. (for floppy devices, the major = 2, and the minor
is shown for informational purposes only):
/dev/fd0d360 (minor = 4)
/dev/fd0h1200 (minor = 8 )
/dev/fd0D360 (minor = 12)
/dev/fd0H360 (minor = 12)
/dev/fd0D720 (minor = 16)
/dev/fd0H720 (minor = 16)
/dev/fd0h360 (minor = 20)
/dev/fd0h720 (minor = 24)
/dev/fd0H1440 (minor = 28)
/dev/fd1d360 (minor = 5)
/dev/fd1h1200 (minor = 9)
/dev/fd1D360 (minor = 13)
/dev/fd1H360 (minor = 13)
/dev/fd1D720 (minor = 17)
/dev/fd1H720 (minor = 17)
/dev/fd1h360 (minor = 21)
/dev/fd1h720 (minor = 25)
/dev/fd1H1440 (minor = 29)
The generic floppy devices, /dev/fd0 and /dev/fd1, will fail to work with fdformat when a non-standard format is being used, or if the format has not been auto-detected earlier. In this case, use setfdprm to load the disk parameters.
For ATAPI IDE floppy driver (also known as LS-120 drives or “Superdisk”
drives) you have to use the floppy.
-n No verify. This option will disable the verification that is performed after the format.
