NAME
     fdformat - format floppy diskette or PCMCIA memory card

SYNOPSIS
     fdformat [-dDeEfHlLmMUqvx] [-b label] [-B filename] [-t dos-
     type] [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     The fdformat utility has  been  superseded  by  rmformat(1),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 encountered. 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  capa-
     city  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 densi-
     ties 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 den-
     sity.

     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 systems.



     -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  sys-
                     tems.



     -q              Quiet; does not print status messages.



     -t dos          Installs an MS-DOS file system and boot sec-
                     tor  formatting.  This  is equivalent to the
                     DOS format command or the -d option.



     -t nec          Installs an NEC-DOS  file  system  and  boot
                     sector  on  the  disk after formatting. 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 (sys-
                     tems 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  com-
                     patibility  with previous versions of fdfor-
                     mat. 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 sys-
     tem  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 sec-
     tor).
