\fBfdformat\fP does a low\-level format on a floppy disk. \fIdevice\fP is usually one of the following (for floppy devices the major = 2, and the minor is shown for informational purposes only):

The generic floppy devices, \fI/dev/fd0\fP and \fI/dev/fd1\fP, will fail to work with \fBfdformat\fP when a non\-standard format is being used, or if the format has not been autodetected earlier. In this case, use \fBsetfdprm\fP(8) to load the disk parameters.
.SH "OPTIONS"
.sp
\fB\-f\fP, \fB\-\-from\fP \fIN\fP
.RS 4
Start at the track \fIN\fP (default is 0).
.RE
.sp
\fB\-t\fP, \fB\-\-to\fP \fIN\fP
.RS 4
Stop at the track \fIN\fP.
.RE
.sp
\fB\-r\fP, \fB\-\-repair\fP \fIN\fP
.RS 4
Try to repair tracks failed during the verification (max \fIN\fP retries).
.RE
.sp
\fB\-n\fP, \fB\-\-no\-verify\fP
.RS 4
Skip the verification that is normally performed after the formatting.
.RE
.sp
\fB\-h\fP, \fB\-\-help\fP
.RS 4
Display help text and exit.
.RE
.sp
\fB\-V\fP, \fB\-\-version\fP
.RS 4
Print version and exit.

.SH "NOTES"
.sp
This utility does not handle USB floppy disk drives. Use \fBufiformat\fP(8) instead.
