3 format \- format a PC floppy diskette
16 allows a user with read-write permission to
18 to format a floppy. Either one of the special floppy devices must be used,
21 or an automatic device may be used with the size of the floppy specified on
22 the command line. Two sizes must be given when formatting a low density
23 diskette in a high density drive. For example:
30 format /dev/fd1 360 1200
35 The first two commands format a 1.2M diskette, the last formats a 360k
36 diskette in a 1.2M drive. A 1.44M drive knows when it's dealing with a low
37 density floppy, so all these commands format a 720k diskette:
43 format /dev/fd0 720 1440
49 No sizes may be specified when using a special floppy device, a size must be
50 specified when using an automatic device.
54 Verify the process by reading each track after formatting it. Formatting is
55 normally blind, the controller has no idea whether it succeeds or not. Use
57 on a new box of cheap diskettes, or on a diskette that may have gone bad.
58 Verifying will increase formatting time by 50%.
63 Numbers will be printed on standard output to show that it is busy. The
64 locations of bad sectors are printed on standard error when verifying. The
65 exit code is zero unless there are too many bad spots.
