       floppy - format floppy disks

       floppy --createrc >/etc/floppy

       floppy --format /dev/fd0

       floppy --format A:


       The floppy utility does low-level formatting of floppy disks.  floppy uses a simple inter-
       face for formatting disks in floppy controller drives and in ATAPI IDE floppy drives, such
       as  LS-120  "Superdisk"	drives.  ATAPI	IDE support requires a patch to the Linux kernel.
       Without a patched kernel floppy can only format disks in floppy controller drives.

       NOTE: Use caution in formatting anything other than standard 3.5" 1.4MB	floppy	disks  in
       ATAPI IDE floppy drives. Most LS-120 drives, for example, accept a request to format 120MB
       high density disks, but most 120MB disks are not designed to be formatted. Low-level  for-
       matting will ruin them permanently.

       floppygtk  is a GTK interface to the floppy utility.  When started from an X terminal win-
       dow, floppy will automatically run floppygtk.

       --probe, -p
	      - Probe for available floppy drives. floppy creates and  displays  a  list  of  all
	      detected floppy drives.

       --createrc, -r
	      -  Print	a configuration file. floppy prints on standard output the results of the
	      --probe option in a configuration file format.  This configuration file  should  be
	      saved as /etc/floppy.

	      - List floppy drives configured in /etc/floppy.

       --capacity, -c
	      -  Show the available format capacities of the floppy drive. Most floppy drives can
	      format disks of different capacities. --capacity lists each available format capac-
	      ity  as  CxBxS  where:  C - number of cylinders, B - blocks per cylinder, S - block
	      size, in bytes.  --capacity also calculates how  much  that  is,	in  kilobytes  or

       --format, -f
	      - Format the disk in the floppy drive.

       --size=CxBxS, -s=CxBxS
	      -  Specify  the size of the disk to format. --format uses the first format capacity
	      reported by --capacity if the --size option is not specified.

       --ext2 - Create an ext2 (Linux) filesystem on the formatted floppy. This  option  requires
	      the e2fsprogs package to be installed. This option simply runs mke2fs after format-
	      ting the floppy disk.

       --fat  - Create a FAT (DOS) filesystem on the formatted floppy. This option  requires  the
	      dosfstools  package  to be installed. This option simply runs mkdosfs after format-
	      ting the floppy disk.

       --noprompt, -n
	      - Suppress verbose output produced by --capacity and --format.  Use  a  raw  output
	      format that can be used by a front-end wrapper that runs floppy on the back-end.

	      - Eject the floppy from the drive (IDE floppy drives only).

       floppy --probe

       This  command  probes  the hardware and reports on the available floppy drives.	A typical
       output from --probe would be:

       floppy 0.12 Copyright 2001, Double Precision, Inc.

       floppy	 /dev/fd0: 3.5" HD
       idefloppy /dev/hda: LS-120 VER5 00 UHD Floppy
       Revision: F523M5A9
       Serial number: 9803M9A03464

       Here, floppy detected a high density floppy drive on /dev/fd0, and an IDE floppy drive  on

       A  configuration  file, /etc/floppy must be created before floppy can format floppy disks.
       This configuration file can be created automatically by the --createrc option.  Each  line
       in  the	configuration file contains the following information: type<TAB>label<TAB>device.
       "<TAB>" is a single ASCII TAB character. "device" is  the  device  entry  for  the  floppy
       drive. floppy requires that all requests for formatting floppies must use only the devices
       that appear in this configuration file. "label"	is  an	alias  for  this  device.  floppy
       accepts	"label:"  instead  of the actual device entry, for example: "floppy --format A:".
       "type" is either "floppy" or "idefloppy".

       The --createrc option sets "A" as the label for the first floppy drive, and  "B"  for  the
       second  floppy drive. If --createrc finds more than two floppy drives, --createrc will use
       "FA", "FB", "FC", and so on.

       Most floppy drives can format disks of different capacities. The --capacity  option  shows
       possible  format capacities on the specified floppy device. A typical IDE floppy drive may
       report the following capacities:

       $ floppy --capacity B:
       Formattable capacities for /dev/hda:
       80x36x512       (1.40 Mb)
       80x30x512       (1.17 Mb)
       56x22x1024      (1.20 Mb)

       A standard floppy drive attached to the floppy controller may report the following capaci-

       $ floppy --capacity A:
       Formattable capacities for /dev/fd0:
       80x36x512       (/dev/fd0H1440, 1.40 Mb)
       80x18x512       (/dev/fd0D720, 720 Kb)
       80x48x512       (/dev/fd0u1920, 1.87 Mb)
       80x28x512       (/dev/fd0u1120, 1.09 Mb)
       80x40x512       (/dev/fd0u1660, 1.56 Mb)
       80x26x512       (/dev/fd0u1040, 1.01 Mb)
       80x46x512       (/dev/fd0u1840, 1.79 Mb)
       80x42x512       (/dev/fd0u1680, 1.64 Mb)

       The  --capacity	option reports each available format capacity as "cylinders x blocks-per-
       cylinder x block size". An IDE floppy drive actually returns a total block count. --capac-
       ity  simply  tries  some  common blocks-per-cylinder values, until it finds one that fits.
       Format capacities of standard floppy drives are obtained from the floppy device driver.

       NOTE: IDE floppy drives may report format capacities only after a disk is inserted.  With-
       out  a  floppy  disk, IDE floppy drives may not report any available format capacities, or
       they may report the primary format capacity that they are designed to format.   For  exam-
       ple,  most  LS-120 drives default to reporting 120mb when there is no disk inserted in the

       $ floppy --capacity A:
       Formattable capacities for /dev/hda:
       6848x36x512     (120.37 Mb)

       CAUTION: do not attempt to format 120Mb media in LS-120 drives. Most LS-120 disks are  not
       user-formattable.   They  are  factory-formatted,  and  attempts  to format them in LS-120
       drives will render them unusable (to be sure, check the label on the floppy  itself).  The
       floppy  utility does not prevent one from trying to use any format capacity the IDE floppy
       drive claims to support. If the drive claims it can format a disk of the  given	capacity,
       floppy will oblige.

       The --format option does a low-level format on the floppy.

       $ ./floppy --format --size=80x36x512 A:
       Formatting 1.40 Mb...   0%

       --size  must  specify  a  geometry returned by --capacity.  If --size is absent, the first
       geometry is selected.

       For floppy controller drives, the status counter will go from 0% to 100%.  With	most  IDE
       floppy  drives  the  counter  will remain at 0% until the format finishes. Some IDE floppy
       drives are capable of reporting format progress status, which will would allow --format to
       count up from 0% to 100%.

       $ ./floppy --format --verify A:

       The  --verify  option  verifies	the  low-level	format. For floppy controller drives, the
       floppy disk is read from start to finish, after the low-level format  concludes.  For  IDE
       floppy  drives,	the format request to the drive will include a request to verify the low-
       level format.

       NOTE: Some IDE floppy drives ignore the verify request, or always  verify  low-level  for-
       mats, whether or not it was requested.

       $ ./floppy --format -V A:

       The  -V option is like --verify except that IDE floppy drive formats are verified manually
       - like floppy controller drive formats - by reading the floppy disk from start to finish.

	      - configuration file.

	      - floppy controller drives.

	      - ATAPI IDE floppy drives.
