path name of a
raw device node for a floppy disk drive (e.g., /dev/rfd0c),
name in an abbreviated form, (e.g., fd0). Note that any geometry constraints
of the device node (minor device number) are meaningless, since
they're overridden by fdformat.
The options are as follows:
-q Suppress any normal output from the command, and
don't ask the
user for confirmation whether to format the floppy

-v Don't format; verify only.

fdformat was developed for 386BSD 0.1 and upgraded to the
new fd(4) floppy
disk driver. It later became part of FreeBSD 1.1, and
was then ported
to OpenBSD 1.2.
The program was contributed by Joerg Wunsch, Dresden, with
Serge Vakulenko and Andrew A. Chernov, Moscow.
