Low-level format a floppy disk
fdformat [options] 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 autodetected earlier. In this case, use setfdprm(8) to load the disk parameters.
Skip the verification that is normally performed after the formatting.
