  If your Linux kernel doesn't understand Macintosh partition tables it
  gives this warning when it can't find a partition table it recognizes.
  To support partitioned media with such kernels, decoding of Mac
  partition tables is done by the HFS filesystem so you should still be
  able to mount the disk.  However, to do so you will need to mount the
  raw device (such as /dev/sdb instead of /dev/sdb4) and use the part
  mount option to indicate which partition you want.

  1133..  CCaann II mmoouunntt mmuullttiippllee HHFFSS ppaarrttiittiioonnss ffrroomm tthhee ssaammee MMaacciinnttoosshh ddiisskk??

  Only if your kernel understands Macintosh partition tables.  It the
  kernel doesn't understand the Macintosh partition table, the HFS
  filesystem must access the raw device.  Therefore, the kernel thinks
  the entire drive is in use and prevents additional mounts on it.

  The HFS filesystem is as capable as the MS-DOS or VFAT filesystems,
  except that certain things can only be done with a file's data fork.

  You ccaann:

  +o  Create, delete and rename directories and data forks of files with
     the caveat that names are case insensitive (so foo and Foo are the
     same file or directory).

  +o  Run Linux executables or shared libraries on an HFS disk if they
     are stored in the data fork of a file.

  +o  Read, write and truncate both forks of files and the Finder's
     metadata of files and directories.

  +o  Mmap data forks of files (and the resource fork if the filesystem
     is mounted with the fork=cap option).

  +o  Toggle the 'w' permission bits (as a group) of data forks.

  +o  Change the i_mtime of files and directories.

  You ccaannnnoott:

  +o  Create, delete or rename resource forks of files or the Finder's
     metadata.  Note, however, that they are created (with defaults
     values), deleted and renamed along with the corresponding data fork
     or directory.

  +o  Run Linux executables or shared libraries on an HFS disk if they
     are stored in the resource fork of a file.

  +o  Mmap the Finder's metadata (when fork=cap) or AppleDouble header
     files (when fork=double or fork=netatalk).

  +o  Change permissions on directories.

  +o  Change the uid or gid of files or directories.

  +o  Set the set-uid, set-gid or sticky permission bits.

  +o  Create multiple links to files.

  +o  Create symlinks, device files, sockets or FIFOs.

  Yes and no.  The software is fully capable of dealing with HFS disks
  of any size.  However, the 400k and 800k diskettes are written in a
  physical format that is incompatible with most non-Macintosh floppy
  drives.  Note also that almost all 400k Macintosh diskettes are MFS,
  not HFS.

  1166..  HHooww ccaann II ffoorrmmaatt aann HHFFSS ffiilleessyysstteemm??

  Robert Leslie ([e-mail]) has written a package for working with
  HFS filesystems (like mtools plus a graphical interface).  One program
  in the package is hformat which can format HFS filesystems.  The
  latest version can be found on the HFS Utilities home page
  <http://www.mars.org/home/rob/proj/hfs/>.

  1177..  HHooww ccaann II ffsscckk aann HHFFSS ffiilleessyysstteemm??

  Right now you'll have to use a Macintosh to do this.  However, Rob
  Leslie is working on an fsck for HFS filesystems.

  nneettaattaallkk??

  To be compatible with netatalk's afpd you will need to use netatalk
  version 1.4b1 or newer and mount the HFS filesystem with the ``afpd''
  mount option.  More information is provided in the ``afpd'' subsection
  of the ``Mount Options'' section of the HFS documentation (HFS.txt if
  you have the stand-alone HFS distribution or
  linux/Documentation/filesystems/hfs.txt if HFS is in your kernel
  source tree.)

  iiccoonnss??

  When using the ``afpd'' mount option the Desktop database on the disk
  is not made available to Netatalk's afpd.  Because of this mounting an
  HFS filesystem across the network to a Macintosh may result in the
  Finder showing generic application and document icons.  Additionally
  double clicking on a document will fail to start the correct
  application.

  If the disk is writable you can make Netatalk build a new Desktop
  database in its own format by holding down the Option key while
  selecting the volume in the Chooser.  If the disk is not writable then
  these problems can be worked around by copying the application to a
  local disk on the Macintosh.
