HFORMAT(1)		    General Commands Manual		    HFORMAT(1)

NAME
       hformat - create	a new HFS filesystem and make it current

SYNOPSIS
       hformat [-f] [-l	label] destination-path	[partition-no]

DESCRIPTION
       hformat is used to write	a new HFS filesystem to	a volume. A UNIX path-
       name to the volume's destination	must be	specified. The destination may
       be  either  a block device or a regular file, but it must already exist
       and be writable.

       An optional label can be	specified to name the volume. The name must be
       between 1-27 characters and cannot contain a colon (:). By default, the
       volume will be named Untitled.

       If the destination medium is partitioned, one  partition	 must  be  se-
       lected to receive the filesystem. If there is only one HFS partition on
       the medium, it will be selected by default. Otherwise, the desired par-
       tition  number  must be specified (as the ordinal nth HFS partition) on
       the command-line. The size of the partition determines the size of  the
       resulting volume.

       Partition  number  0  can be specified to format	the entire medium as a
       single filesystem without a partition map, erasing any existing	parti-
       tion  information.  Since  this will destroy all	the partitions,	the -f
       option must be specified	to force this operation	 if  the  medium  cur-
       rently contains a partition map.

       If  the medium is not partitioned (or if	partition 0 is specified), the
       size or capacity	of the medium determines the  size  of	the  resulting
       volume.

       The  new	 volume	 will be empty and will	become "current" so subsequent
       commands	will refer to it. The current working directory	for the	volume
       is set to the root of the volume.

EXAMPLES
       % hformat /dev/fd0
	      If a floppy disk is available as /dev/fd0, this formats the disk
	      as an HFS	volume named Untitled.	(N.B. The floppy must  already
	      have received a low-level	format by other	means.)

       % dd if=/dev/zero of=disk.hfs bs=1k count=800
       % hformat -l "Test Disk"	disk.hfs
	      This  sequence  creates  an  800K	 HFS  volume image in the file
	      disk.hfs in the current directory, and names it Test Disk.

       % hformat -l "Loma Prieta" /dev/sd2 1
	      If a SCSI	disk is	available as /dev/sd2,	this  initializes  the
	      first  HFS partition on the disk (which must already exist) with
	      a	new filesystem,	naming the resulting volume Loma Prieta.

       % hformat -f /dev/sd2 0
	      This causes the medium accessible	as /dev/sd2 to be  reformatted
	      as a single HFS volume, ignoring and erasing any existing	parti-
	      tion information on the medium. The -f option must be  specified
	      if  the  medium  is currently partitioned; otherwise the command
	      will fail.

NOTES
       This command does not create or alter partition maps, although  it  can
       erase  them (as described above). Any partition number specified	on the
       command line must already exist.

       The smallest volume size	which can be formatted with hformat is 800K.
