Martin,
   Here's what I've learned,  mostly from the Unix section on Apple's
OS X forums:

1) Apple does not support ext2 or ext3. To the best of their knowledge
everyone tells me that this has always been the case.

2) There is a Sourceforge project that provides an ext2 driver for OS
X 10.3 but it doesn't work with 10.4, the current version of OS X.

http://sourceforge.net/projects/ext2fsx

3) It is not possible, at least with Applie's GUI called 'Disk
Utility' to use the PC Partition Scheme and format a 1394 drive with
anything other than FAT32.

4) It is possible using Disk Utility to use the Apple Partition Scheme
and format a 1394 drive with a number of Apple HFSP formats.

5) It is possible to get Linux to recognise the above formats if you
enable the Apple Partition option in the kernel.

6) I have not yet determined if it is possible to mount the HFS+
partition, but I'm told it is by one fellow in the Apple forums.

7) One downside of using Apple's Disk Utility when doing FAT32
partitions is that fdisk complains that partitions do not end on
cylinder boundaries. I do not know if this is really a problem but I
do not like the warning.

8) Worst of all, so far hpmount, part of the hfsplustools pckage says
it won't mount the HFS+ partitions created by the Mac.

9) There is something called mac-fdisk but it won't build on my AMD64
platform. It does build on IA32 but I don't have 1394 in that box.

   I own a copy of System Commander for Windows which includes
Partition Commander but it won't work with 1394 drives. Only EIDE.

   So, some headway, but still no real good results.

Cheers,
Mark
