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  for‐
38       mat  has  not been autodetected earlier.  In this case, use setfdprm(8)
39       to load the disk parameters.
