13.if n .sp
14..
15.B Format
16allows a user with read-write permission to
17.I device
18to format a floppy. Either one of the special floppy devices must be used,
19see
20.BR fd (4),
21or an automatic device may be used with the size of the floppy specified on
22the command line. Two sizes must be given when formatting a low density
23diskette in a high density drive. For example:
24.PP
25.RS
26.ft B
27.nf
28format /dev/at1
29format /dev/fd1 1200
30format /dev/fd1 360 1200
31.fi
32.ft P
33.RE
34.PP
35The first two commands format a 1.2M diskette, the last formats a 360k
36diskette in a 1.2M drive. A 1.44M drive knows when it's dealing with a low
37density floppy, so all these commands format a 720k diskette:
38.PP
39.RS
40.ft B
41.nf
42format /dev/fd0 720
43format /dev/fd0 720 1440
44format /dev/ps0
45.fi
46.ft P
47.RE
48.PP
49No sizes may be specified when using a special floppy device, a size must be
50specified when using an automatic device.
51.SH OPTIONS
52.TP
53.B \-v
54Verify the process by reading each track after formatting it. Formatting is
55normally blind, the controller has no idea whether it succeeds or not. Use
56.B \-v
57on a new box of cheap diskettes, or on a diskette that may have gone bad.
58Verifying will increase formatting time by 50%.
59.SH "SEE ALSO"
60.BR mkfs (1),
61.BR fd (4).
62.SH DIAGNOSTICS
63Numbers will be printed on standard output to show that it is busy. The
64locations of bad sectors are printed on standard error when verifying. The
65exit code is zero unless there are too many bad spots.
