NAME
       fdformat - format floppy diskette or PCMCIA memory card

SYNOPSIS
       fdformat [-dDeEfHlLmMUqvx] [-b label] [-B filename]
	    [-t dostype] [devname]

DESCRIPTION
       The  fdformat  utility has been superseded by rmformat(1), which provides most but not all
       of fdformat's functionality.

       fdformat is used to format diskettes and PCMCIA memory cards. All new blank  diskettes  or
       PCMCIA memory cards must be formatted before they can be used.

       fdformat formats and verifies the media and indicates whether any bad sectors were encoun-
       tered. All existing data on the diskette or PCMCIA memory card, if any,	is  destroyed  by
       formatting. If no device name is given, fdformat uses the diskette as a default.

       By  default,  fdformat uses the configured capacity of the drive to format the diskette. A
       3.5 inch high-density drive uses diskettes with a formatted capacity  of  1.44MB.  A  5.25
       inch high-density drive uses diskettes with a formatted capacity of 1.2MB. In either case,
       a density option does not have to be specified to fdformat. However, a density option must
       be specified when using a diskette with a lower capacity than the drive's default. Use the
       -H option to format high-density diskettes (1.44MB capacity) in an extra-high-density (ED)
       drive.  Use  the  -D option, the -l option, or the -L option to format double- density (or
       low-density) diskettes (720KB capacity) in an HD or ED  drive.  To  format  medium-density
       diskettes  (1.2MB  capacity), use the -M option with -t nec (this is the same as using the
       -m option with -t nec).

       Extended  density  uses	double-sided,  extended-density  or  extra-high-density   (DS/ED)
       diskettes.  Medium  and	high  densities  use  the  same media: double-sided, high-density
       (DS/HD) diskettes. Double (low) density uses double-sided, double-density (DS/DD

       D) diskettes. Substituting diskettes of one density for diskettes of either  a  higher  or
       lower  density  generally  does	not  work.  Data  integrity  cannot be assured whenever a
       diskette is formatted to a capacity not matching its density.

       A PCMCIA memory card with densities from 512KB to 64MB may be formatted.

       fdformat writes new identification and data fields for each sector on  all  tracks  unless
       the  -x	option	is  specified. For diskettes, each sector is verified if the -v option is
       specified.

       After formatting and verifying, fdformat writes an operating-system label on block 0.  Use
       the  -t dos option (same as the -d option) to put an MS-DOS file system on the diskette or
       PCMCIA memory card after the format is done. Use the -t nec  option  with  the  -M  option
       (same  as  the -m option) to put an NEC-DOS file system on a diskette. Otherwise, fdformat
       writes a SunOS label in block 0.

OPTIONS
       The following options are supported:

       -b label       Labels the media with volume label. A SunOS volume label is restricted to 8
		      characters. A DOS volume label is restricted to 11 upper-case characters.

       -B filename    Installs special boot loader in filename on an MS-DOS diskette. This option
		      is only meaningful when the -d option (or -t dos) is also specified.

       -D	      Formats a 720KB (3.5 inch) or 360KB  (5.25  inch)  double-density  diskette
		      (same as the -l or -L options). This is the default for double-density type
		      drives. It is needed if the drive is a high- or extended-density type.

       -e	      Ejects the diskette when done. This feature is not available  on	all  sys-
		      tems.

       -E	      Formats  a 2.88MB (3.5 inch) extended-density diskette. This is the default
		      for extended-density type drives.

       -f	      Forces formatting, that is, this	option	does  not  ask	for  confirmation
		      before starting format.

       -H	      Formats  a  1.44MB  (3.5	inch) or 1.2MB (5.25 inch) high-density diskette.
		      This is the default for high-density type drives; it is needed if the drive
		      is the extended-density type.

       -M	      Writes  a 1.2MB (3.5 inch) medium-density format on a high-density diskette
		      (use only with the -t nec option). This is the same as using -m.

		      This feature is not available on all systems.

       -q	      Quiet; does not print status messages.

       -t dos	      Installs an MS-DOS file system and boot sector formatting. This is  equiva-
		      lent to the DOS format command or the -d option.

       -t nec	      Installs	an  NEC-DOS file system and boot sector on the disk after format-
		      ting. This should be used only with the -M  option.  This  feature  is  not
		      available on all systems.

       -U	      Performs umount on any file systems and then formats. See mount(1M).

       -v	      Verifies each block of the diskette after the format.

       -x	      Skips the format and only writes a SunOS label or an MS-DOS file system.

OPERANDS
       The following operands are supported:

       devname	  Replaces devname with rdiskette0 (systems without volume management) or floppy0
		  (systems with volume management) to use the first drive or rdiskette1  (systems
		  without  volume  management) or floppy1 (systems with volume management) to use
		  the second drive. If devname is omitted, the first drive,  if  one  exists,  is
		  used.  For  PCMCIA  memory  cards, replace devname with the device name for the
		  PCMCIA memory card which resides in /dev/rdsk/cNtNdNsN or /dev/dsk/cNtNdNsN. If
		  devname is omitted, the default diskette drive, if one exists, is used.

		  If devname is omitted, the default diskette drive, if one exists, will be used.
		  N represents a decimal number and can be specified as follows:

		  cN	Controller N

		  tN	Technology type N:

			  0x1	    ROM
			  0x2	    OTPROM
			  0x3	    EPROM
			  0x4	    EEPROM
			  0x5	    FLASH
			  0x6	    SRAM
			  0x7	    DRAM

		  dN	Technology region in type N.

		  sN	Slice N.

		  The following options are provided for compatibility with previous versions  of
		  fdformat. Their use is discouraged.

		  -d	Formats an MS-DOS floppy diskette or PCMCIA memory card (same as -t dos).
			This is equivalent to the MS-DOS FORMAT command.

		  -l	Formats a 720KB (3.5 inch) or 360KB (5.25 inch)  double-density  diskette
			(same  as  -D or -L). This is the default for double-density type drives;
			it is needed if the drive is the high- or extended-density type.

		  -L	Formats a 720KB (3.5 inch) or 360KB (5.25 inch)  double-density  diskette
			(same as -l or -D). This is the default for double-density type drives.

		  -m	Writes	a  1.2	MB  (3.5  inch)  medium- density format on a high-density
			diskette (use only with the -t nec option). This is the same as using -M.
			This feature is not available on all systems.

NOTES
       A  diskette  or	PCMCIA	memory card containing a ufs file system created on a SPARC based
       system (by using fdformat and newfs(1M)), is not identical to a diskette or PCMCIA  memory
       card  containing  a ufs file system created on an x86 based system. Do not interchange ufs
       diskettes or memory cards between these platforms. Use cpio(1) or tar(1) to transfer files
       on  diskettes  or  memory  cards  between them. A diskette or PCMCIA memory card formatted
       using the -t dos option (or -d) for MS-DOS does not have the necessary system  files,  and
       is therefore not bootable. Trying to boot from it on a PC produces the following message:

	 Non-System disk or disk error.
	 Replace and strike any key when ready

BUGS
       Currently, bad sector mapping is not supported on floppy diskettes or PCMCIA memory cards.
       Therefore, a diskette or memory card is unusable if fdformat finds an error (bad sector).
