32 .Nd format floppy disks
48 .Op Fl t Ar steps_per_track
53 utility formats a floppy disk at device
56 may be given either with a full path
57 name of a device node for a floppy disk drive
60 or a default name in an abbreviated form
63 In the latter case, the name is constructed by prepending
69 Note that any geometry constraints of the device node
71 are meaningless, since they're overridden by
74 The options are as follows:
75 .Bl -tag -width 10n -offset indent
77 Suppress any normal output from the command, and don't ask the
78 user for a confirmation whether to format the floppy disk at
81 Suppress confirmation request by automagically responding "yes", but still
84 The normal way to specify the desired formatting parameters.
86 is the number of kilobytes to format.
87 Valid choices are 360, 720, 800, 820,
88 1200, 1440, 1480 or 1720.
90 Don't verify floppy after formatting.
92 Don't format, verify only.
94 Number of cylinders: 40 or 80.
96 Number of sectors per track: 9, 10, 15 or 18.
98 Number of floppy heads: 1 or 2.
100 Data rate: 250, 300 or 500 kbps.
106 Sector size: 0=128, 1=256, 2=512 bytes.
109 .It Fl t Ar steps_per_track
110 Number of steps per track.
111 An alternate method to specify the geometry data to write to the floppy disk.
116 flag has not been specified, the user is asked for a confirmation
117 of the intended formatting process.
118 In order to continue, an answer
125 does only perform low-level formatting. In case you wish to create
126 a file system on the medium, see the commands
138 has been specified, a single letter is printed to standard output
139 to inform the user about the progress of work.
142 is printed when the track(s) is being formatted, then a
144 while it's being verified, and if an error has been detected, it
145 will finally change to
147 Detailed status information (cylinder, head and sector number, and the
148 exact cause of the error) will then be printed for up to 10 errors.
150 An exit status of 0 is returned upon successful operation.
152 1 is returned on any errors during floppy formatting, and an exit status
153 of 2 reflects invalid arguments given to the program (along with an
154 appropriate information written to diagnostic output).
