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.
40
41       For ATAPI IDE floppy driver (also known as LS-120 drives or "Superdisk"
42       drives) you have to use the floppy(8).

OPTIONS

46       -n     No  verify.   This  option will disable the verification that is
47              performed after the format.
