	48	.Sh DESCRIPTION
	49	.Nm Fdformat
	50	formats a floppy disk at device
	51	.Ar device_name .
	52	.Ar Device_name
	53	should be a character device; it may be given either with a full path
	54	name of a raw device node for a floppy disk drive
	55	.Pq e.\ g. Pa /dev/rfd0 ,
	56	or default name in an abbreviated form
	57	.Pq e.\ g. Em fd0 .
	58	In the latter case, the name is constructed by prepending
	59	.Pa /dev/r
	60	and appending a
	61	.Em .capacity
	62	to the
	63	.Ar device_name .
	64	Note that any geometry constraints of the device node
	65	.Pq minor device number
	66	are meaningless, since they're overridden by
	67	.Nm fdformat .
	68	.Pp
	69	The options are as follows:
	70	.Bl -tag -width 10n -offset indent
	71	.It Fl q
	72	supress any normal output from the command, and don't ask the
	73	user for a confirmation whether to format the floppy disk at
	74	.Ar device_name .
	75	.It Fl f Ar capacity
	76	The normal way to specify the desired formatting parameters.
	77	.Ar Capacity
	78	is the number of kilobytes to format.
	79	.It Fl n
	80	Don't verify floppy after formatting.
	81	.It Fl v
	82	Don't format, verify only.
	83	.It Fl c Ar cyls
	84	.It Fl s Ar secs
	85	.It Fl h Ar heads
	86	.It Fl r Ar rate
	87	.It Fl g Ar gap3len
	88	.It Fl i Ar intleave
	89	.It Fl S Ar secshft
	90	.It Fl F Ar fillbyte
	91	.It Fl t Ar steps_per_track
	92	An alternate method to specify the geometry data to write to the floppy disk.
	93	.El
	94
	95	If the
	96	.Fl q
	97	flag has not been specified, the user is asked for a confirmation
	98	of the intended formatting process. In order to continue, an answer
	99	of
	100	.Dq y
	101	must be given.
	102	.Sh DIAGNOSTICS
	103	Unless
	104	.Fl q
	105	has been specified, a single letter is printed to standard output
	106	to inform the user about the progress of work.
	107	First, an
	108	.Sq Em F
	109	is printed when the track(s) is being formatted, then a
	110	.Sq Em V
	111	while it's being verified, and if an error has been detected, it
	112	will finally change to
	113	.Sq Em E .
	114	.Pp
	115	An exit status of 0 is returned upon successful operation. Exit status
	116	1 is returned on any errors during floppy formatting, and an exit status
	117	of 2 reflects invalid arguments given to the program (along with an
	118	appropriate information written to diagnostic output).
	119	.Sh SEE ALSO
	120	.Xr fd 4 .
	121	.Sh HISTORY
	122	.Nm Fdformat
	123	has been developed for 386BSD 0.1
	124	and upgraded to the new
	125	.Xr fd 4
	126	floppy disk driver. It later became part of the
	127	.Em FreeBSD
	128	system, release 1.1.
	129	.Sh AUTHOR
	130	The program has been contributed by
	131	.if n Joerg Wunsch,
	132	.if t J\(:org Wunsch,
	133	Dresden, with changes by Serge Vakulenko and Andrew A. Chernov, Moscow.
