HFORMAT(1)                                                          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
       selected  to receive the filesystem. If there is only one HFS partition
       on the medium, it will be selected by default. Otherwise,  the  desired
       partition  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.
