NAME
  fddisk - FDI disk maintenance utility

SYNOPSIS
  /sbin/fddisk options special

OPTIONS
  -f  Unless this option is specified, an attempt to format or to install a
      file system fails in two cases.  The first failure occurs when the
      device has been opened since the media was inserted.  The second
      failure occurs if the device is currently opened by another process.

  -fmt
      Formats the media to the density appropriate for that media.

  -hexd PSN
      Copies a hex dump of sector number PSN to stdout.

  -i nnn [ccc]
      Uses the interleave factor nnn for formatting.  If specified, ccc
      indicates an additional intercylinder interleave.

  -pchd
      Copies a packed-C hex dump of the entire disk to stdout.

  -s  Specifies silent mode.  This option blocks informational messages from
      appearing on stderr.

  -test
      Reads the entire media.  The command fails if the utility finds a bad
      sector.

  -wait
      Waits for media to be inserted into the drive if none is present.

  -waitn
      Waits for new media to be inserted into the drive if none is present or
      if the current media has been opened since it was last inserted.

  -what
      Reads the disk and reports on the format of the disk.

OPERANDS
  special
      Specifies an unmounted, raw device pathname.  This device must be an
      FDI interface (fd).

DESCRIPTION
  The fddisk utility, an FDI (integrated Floppy Disk Interface) disk
  maintenance program, can format a floppy disk, scan a floppy disk for bad
  blocks, and read and write selected blocks.  It can be used in shell
  scripts for checking the status of floppy disks.  Such status checks
  include checking for or waiting for the presence of media, and checking for
  or waiting for the user to change the media.

RESTRICTIONS
  The fddisk utility has the following restrictions:

    ·  You must have read/write access to the device.

    ·  The device must not be mounted.

    ·  The program can only be used with a 3.5-inch floppy disk in the RX26
       drive.

    ·  In some cases, it might not be possible to format a floppy disk at a
       higher density than it is already formatted.  If this situation
       occurs, the floppy disk must be bulk erased before it can be
       reformatted at a higher density.

EXAMPLES
   1.  This example formats a floppy disk in drive zero:
	    # /sbin/fddisk -fmt /dev/rdisk/floppy0a

   2.  This example formats a floppy disk in drive zero when the disk has
       been read or written since it was inserted into the drive:
	    # /sbin/fddisk -fmt -f /dev/rdisk/floppy0a

SEE ALSO
  Commands: mount(8), restore(8), uerf(8)

  Files: fd(7)
