hformat - create a new HFS filesystem and make it current
is used to write a new HFS filesystem to a volume. A UNIX pathname 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
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
HFS partition) on the command-line. The size of the partition determines the
size of the resulting volume.
can be specified to format the entire medium as a single filesystem without a
partition map, erasing any existing partition information. Since this will
destroy all the partitions, the
option must be specified to force this operation if the medium currently
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.

- % 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
in the current directory, and names it

If a SCSI disk is available as
this initializes the first HFS partition on the disk (which must already
exist) with a new filesystem, naming the resulting volume
- % hformat -f /dev/sd2 0
This causes the medium accessible as
to be reformatted as a single HFS volume, ignoring and erasing any existing
partition information on the medium. The
option must be specified if the medium is currently partitioned; otherwise the
command will fail.
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.
