NetBSD 6.1.5 - man page for fdformat (netbsd section 1)

FDFORMAT(1)			   BSD General Commands Manual			      FDFORMAT(1)

     fdformat -- format a floppy diskette

     fdformat [-f device] [-t type] [-n] [-B nbps] [-S nspt] [-T ntrk] [-C ncyl] [-P stepspercyl]
	      [-G gaplen] [-F fillbyte] [-X xfer_rate] [-I interleave]

     The fdformat 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

     As the each track of the floppy diskette is formatted, it is read to verify the format was

     The fdformat utility does not create a filesystem of any kind.  Use tools like newfs(8),
     newfs_msdos(8), or 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.

     Available command-line flags are:
     -f device
	     Format the floppy using device instead of the default /dev/rfd0a.
     -t type
	     Format the floppy using parameters for the diskette named type in /etc/floppytab
	     instead of the device default parameters.
     -n      Do not verify each track as it is read.
     -B nbps
	     Set the number of bytes per sector for the formatted diskette.
     -S nspt
	     Set the number of sectors per track for the formatted diskette.
     -T ntrk
	     Set the number of tracks (heads) per cylinder for the formatted diskette.
     -C ncyl
	     Set the number of cylinders for the formatted diskette.
     -P stepspercyl
	     Set the number of motor steps per cylinder for the formatted diskette.
     -G gaplen
	     Set the sector gap length for the formatted diskette.
     -F fillbyte
	     Set the fill byte for the formatted diskette.
     -X xfer_rate
	     Set the bit transfer rate for the formatted diskette.
     -I interleave
	     Set the interleave factor for the formatted diskette.

     fdc(4) (amiga, i386 and sparc ports)

     The fdformat utility appeared in NetBSD 1.3.

     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 can-
     not successfully verify the formatted diskette except at the diskette's normal density.
