SYNOPSIS

9       fdformat [options] device
10

DESCRIPTION

12       fdformat does a low-level format on a floppy disk. device is usually
13       one of the following (for floppy devices the major = 2, and the minor
14       is shown for informational purposes only):
15
16           /dev/fd0d360  (minor = 4)
17           /dev/fd0h1200 (minor = 8)
18           /dev/fd0D360  (minor = 12)
19           /dev/fd0H360  (minor = 12)
20           /dev/fd0D720  (minor = 16)
21           /dev/fd0H720  (minor = 16)
22           /dev/fd0h360  (minor = 20)
23           /dev/fd0h720  (minor = 24)
24           /dev/fd0H1440 (minor = 28)
25
26           /dev/fd1d360 (minor = 5)
27           /dev/fd1h1200 (minor = 9)
28           /dev/fd1D360 (minor = 13)
29           /dev/fd1H360 (minor = 13)
30           /dev/fd1D720 (minor = 17)
31           /dev/fd1H720 (minor = 17)
32           /dev/fd1h360 (minor = 21)
33           /dev/fd1h720 (minor = 25)
34           /dev/fd1H1440 (minor = 29)
35
36       The generic floppy devices, /dev/fd0 and /dev/fd1, will fail to work
37       with fdformat when a non-standard format is being used, or if the
38       format has not been autodetected earlier. In this case, use setfdprm(8)
39       to load the disk parameters.
