FDFORMAT(8)						     Linux Programmer's Manual						       FDFORMAT(8)

NAME

       fdformat - Low-level formats a floppy disk

SYNOPSIS

       fdformat [ -n ] device

DESCRIPTION

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

	      /dev/fd0d360  (minor = 4)
	      /dev/fd0h1200 (minor = 8)
	      /dev/fd0D360  (minor = 12)
	      /dev/fd0H360  (minor = 12)
	      /dev/fd0D720  (minor = 16)
	      /dev/fd0H720  (minor = 16)
	      /dev/fd0h360  (minor = 20)
	      /dev/fd0h720  (minor = 24)
	      /dev/fd0H1440 (minor = 28)

	      /dev/fd1d360  (minor = 5)
	      /dev/fd1h1200 (minor = 9)
	      /dev/fd1D360  (minor = 13)
	      /dev/fd1H360  (minor = 13)
	      /dev/fd1D720  (minor = 17)
	      /dev/fd1H720  (minor = 17)
	      /dev/fd1h360  (minor = 21)
	      /dev/fd1h720  (minor = 25)
	      /dev/fd1H1440 (minor = 29)

       The generic floppy devices, /dev/fd0 and /dev/fd1, will fail to work with fdformat when a non-standard format is being used, or if the for-
       mat has not been autodetected earlier.  In this case, use setfdprm(8) to load the disk parameters.

OPTIONS

       -n     No verify.  This option will disable the verification that is performed after the format.
