.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility formats a floppy diskette.
|
|
With no arguments, it formats the default floppy device with the default
|
|
density parameters (as provided by the floppy diskette device driver).
|
|
.Pp
|
|
As the each track of the floppy diskette is formatted, it is read to
|
|
verify the format was successful. A status is printed for each track.
|
|
.Em F
|
|
indicates a track was formatted.
|
|
.Em V
|
|
indicates the track was successfully verified.
|
|
.Em E
|
|
indicates an error in formatting or verifying a track.
|
|
.Pp
|
|
Available command-line flags are:
|
|
.Bl -tag -width indent -compact
|
|
.It Fl f Ar device
|
|
Format the floppy using
|
|
.Ar device
|
|
instead of the default
|
|
.Pa /dev/rfd0a .
|
|
.It Fl t Ar type
|
|
Format the floppy using parameters for the diskette named
|
|
.Ar type
|
|
in
|
|
.Pa /etc/floppytab
|
|
instead of the device default parameters.
|
|
.It Fl n
|
|
Do not verify each track as it is read.
|
|
.It Fl B Ar nbps
|
|
Set the number of bytes per sector for the formatted diskette.
|
|
.It Fl S Ar nspt
|
|
Set the number of sectors per track for the formatted diskette.
|
|
.It Fl T Ar ntrk
|
|
Set the number of tracks (heads) per cylinder for the formatted diskette.
|
|
.It Fl C Ar ncyl
|
|
Set the number of cylinders for the formatted diskette.
|
|
.It Fl P Ar stepspercyl
|
|
Set the number of motor steps per cylinder for the formatted diskette.
|
|
.It Fl G Ar gaplen
|
|
Set the sector gap length for the formatted diskette.
|
|
.It Fl F Ar fillbyte
|
|
Set the fill byte for the formatted diskette.
|
|
.It Fl X Ar xfer_rate
|
|
Set the bit transfer rate for the formatted diskette.
|
|
.It Fl I Ar interleave
|
|
Set the interleave factor for the formatted diskette.
|
|
.El
|
|
.Sh BUGS
|
|
Some floppy drive units have physical
|
|
diskette format sensors which automatically select a diskette
|
|
density for reading. Such drives can format at alternate densities, but
|
|
they cannot successfully verify the formatted diskette except at the
|
|
diskette's normal density.
