NAME

       mformat - mtools utility to add a DOS file system to a low-level formatted diskette

SYNOPSIS

       mformat [-t tracks] [-h heads] [-s vectors] [-l volumelabel] drive:

OPTIONS

       Specifies the number of tracks (not cylinders) on the diskette.	Specifies the number of heads (sides) on the diskette.	Specifies the num-
       ber of sectors per track.  Specifies the volume label.  This is an optional option.

DESCRIPTION

									  Note

       You must specify the floppy disk storage device that is to be formatted.  If you do not specify a device, or if a device is not found,  the
       command may incorrectly format a SCSI device which could be a system or data disk.

       The  mformat command adds a minimal DOS compatible file system (boot sector, FAT, and root directory) to a UNIX formatted diskette.  If the
       diskette is unformatted, you must low-format the disk. You can do this with a PC system, or on Tru64 UNIX using either the scu  utility	or
       the  fddisk  utility, depending on your floppy drive.  Tru64 UNIX supports both FDI and SCSI attached 3.5" floppy drives with DD, HD, or ED
       media.  Not all floppy drives are compatible with ED media.

       The following track/head/sector values are supported:

       ---------------------------------------------------------------
       Media		Capacity	     Tracks   Heads   Sectors
       type    KB/MB	Bytes	   Sectors   -t       -h      -s
       ---------------------------------------------------------------
       DD      720KB	737280	   1440      80       2       9
       HD      1.44MB	1474560    2880      80       2       18
       ED      2.88MB	2949120    5760      80       2       36
       ---------------------------------------------------------------

       To format a diskette for other than the ED 2.88MB default capacity, you must specify the number of sectors per track with the -s option. No
       error is returned if you use mformat to put an ED file system onto an HD floppy, but you will get errors from other utilities if you try to
       write beyond the physical end of the media.

RESTRICTIONS

       The following restrictions apply: The mformat command requires a low-level format utility from UNIX.  The mformat command does  not  detect
       (or record) bad block information.

EXIT STATUS

       The following exit values are returned: Success.  Failure.

EXAMPLES

       In  the	following example, a SCSI floppy diskette is formatted at the ED 2.88MB capacity, then a DOS file system is initialized with mfor-
       mat: $ /sbin/scu -f /dev/rdisk/dsk/6a format density ED $ mformat a: In the following example, an FDI floppy diskette is formatted  at  the
       HD  1.44MB  capacity, then a DOS file system is initialized with mformat, a file is copied to the diskette, and the mdir command is used to
       check the contents of the diskette.  The mlabel command is used to add a label and mdir is used	to  again  check  the  diskette  contents.
       Finally, a DD file system is placed on the diskette, mcopy is used to place a file on it, and mdir is used to verify the diskette contents:

	      $ fddisk -fmt /dev/rfd0a

	      NOTE:  Setting interleave factor to ``-i2:4''.
		     Use  ``-i<nnn>[:<ccc>]''  option  to  override.  Disk type: 3.50 inch, HD	(1.44MB) Number of sectors per track: 18 Number of
	      surfaces:   2 Number of cylinders: 80 Sector size:  512 interleave factor:  2:4 Formatting disk...  Percentage complete:
	       Format complete, checking...
	       Quick check of disk passes OK.

	      command,	followed  by  the  mformat  command.   Once  it  is formatted by both the scu and mformat commands, it is ready for use: $
	      /sbin/scu -f /dev/disk/floppy format density ED $ mformat -t 80 -h 2 -s 36 a:
