NAME

       floppy - floppy disk interface

SYNOPSIS

       bind -a #f /dev

       /dev/fd0disk
       /dev/fd0ctl
       /dev/fd1disk
       /dev/fd1ctl
       /dev/fd2disk
       /dev/fd2ctl
       /dev/fd3disk
       /dev/fd3ctl

DESCRIPTION

       The floppy disk interface serves a one-level directory giving access to up to four floppy disk drives.  Each drive is represented by a data
       and control file.  There are no partitions.

       Messages accepted by the ctl file include:

       eject  Eject the floppy, if possible.

       reset  Reset the drive.

       format type
	      (Not on the Nextstation) Format the floppy.  The type sets the density and type of disk to be formatted; see format in prep(8).

       A read of the ctl file returns a string describing the form factor of the disk, one of 31/2DD, 31/2HD, 51/4DD, or 51/4HD.

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.
