.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
The
.Nn
utility does not create a filesystem of any kind. Use tools like
.Xr newfs 8 ,
.Xr newfs_msdos 8 
or
.Xr mformat 1
(part of the pkgsrc/sysutils/mtools package) depending on what filesystem
type you want to use on the floppy disk to do so.
.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.
