Mounting OS-X "Unix" filesystems on Linux

Mounting OS-X "Unix" filesystems on Linux

[John Kodis]

I'm trying to mount an OS-X Unix filesystem on Linux.  I haven't had
any luck at this, and wondered whether this is a known problem, or if
I'm doing something wrong.

I formatted a zip disk on a Mac OS-X, selecting the "Unix" filesystem
type and no partitions.  I then inserted this disk in the /dev/hdd,
the zip drive on my PC.  I tried mounting hdd and hdd1 through hdd4
using types of auto, ufs, udf, sysv, and one or two others, all to no
avail.

My guess is that you'll probably need to compile support for 'advanced 
partitions', as you can find in menuconfig under Filesystems - Partition 
Types. I have no idea which one, though. That'll probably trail and error.

That's what I was missing.  I can mount a Mac OS-X "Unix" filesystem
on the Linux 2.4.9-7 kernel supplied with RHL 7.2, but I have to
specify a type of ufs and supply both the ro and ufstype=openstep
options to the mount command.  Too bad about the lack of write
support, but I'm sure someone out there is working on that.  Thanks
for your help.

Try fdisk(8) on it, it might tell you of any strange partitioning. Or the
Mac might have written to the device (not a partition). Get hold of the
first Kb or so of each partition, file(1) might be able to find out what it
is.

Good luck!
