Mount HFS+
webjay
It's a LaCie 500gb USB drive. I can mount and rw on my Mac.
# mount -t hfsplus -r /dev/sda /mnt/usbdisk
mount: wrong fs type, bad option, bad superblock on /dev/sda,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
# dmesg | tail
hfs: unable to find HFS+ superblock
#fdisk -l:
Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 1 60802 488386583+ ee EFI GPT
Thanks, Jacob

Make sure hfsplus module is loaded with modprobe hfsplus.
It should work, as I mounted my HFS+ drive on Debian.
One gotcha, make sure you disable journalling on the HFS+ partition in OS X if you wish to mount it rw on Linux.

I have loaded the kernel module with:
# modprobe hfsplus
I think the problem might be that the partition table is GUID.

Shouldn't this be sda1? Just a thought, I do not use
HFS+.

result? Corruption for both linux and mac r/w attempts?

No, I tried that with the same result.
I think mount picks the first available.

Note that Apple partitioning is different from PC partitioning.
When mounting a hfs+ partition, it looks like you have 4 or 10
partitions, only one of them (possibly sda2 or sda4) is usable, all the
others appear to have zero length.
I once saw this in a partitioning program of another distro; in Debian
I haven't found a way yet to make these partitions visible.

No, it doesn't do that (well it never did for me, anyway).
I agree you certainly don't want to mount /dev/sda (without a number
appended).

Well iirc they don't have zero length, but contain stuff like drivers or
so (I'm not sure whether that is just a relict of old pre-OSX MacOS
times, though, so nowadays hey could possibly really be empty).

You just need kernel support (either as module or compiled in). The
kernel configuration variable is CONFIG_MAC_PARTITION (for mac
partitions, anyway), should you compile it yourself.
linux-image-2.6.18-5-486 does have that compiled in already, as can be
seen in /boot/config-2.6.18-5-486
If your /dev is being handled by udev (as is the case for etch), then
you can easily check whether the kernel understands the partition table:
if there's not only a /dev/sda, but also /dev/sda[1-9]* device files
present after attaching the disk, then the kernel understands the
partitioning just fine (you can also check kern.log).
I guess you mean that you haven't found a way to get a partition listing
with sizes. On Debian on Macs, the package "mac-fdisk" is being
installed automatically (at least that was the case with woody) which
provides an "fdisk" program which could handle mac partition tables;
packages.debian.org says that this package is only available for
powerpc; strange, I don't see any reason for this (maybe it has some
endianness bugs? maybe it's just because it provides a binary of the
same name as the x86 "util-linux" package? If it's just the latter, you
could probably recompile the mac-fdisk sources locally (not as .deb) and
use that).
I'd just do an ls /dev/sda?* and then try to mount every shown partition
in turn until you've found the right one.

# mount -t hfsplus /dev/sda2 /mnt/usbdisk
In /etc/fstab I have:
/dev/sda2 /mnt/usbdisk hfsplus rw,user,noauto 0 0
And to fix some ownership issues I did this:
# chgrp -R users /mnt/usbdisk
Thanks for your help everyone :)

Yet, let me show things a little clearer.
I used to work with SUSE formerly, and in the Partitioner (part of
YaST, their configuration utility) my HFS+-formatted USB stick shows up
like this:
http://home.kpnplanet.nl/~shi...@kpnplanet.nl/suse_partitioner.png
Note that the USB stick has created sda1 through sda9, and it is
accessible through sda9 !
In Debian I found that gparted can make this visible, have a look at
this screenshot of gparted:
http://home.kpnplanet.nl/~shi...@kpnplanet.nl/gparted.png
The USB stick was partitioned with Mac's Disk Utility, with the option
to install drivers for OS9.
Without this option, only sda1`through sda4 are created, and the USB
drive used to be accessible through sda2.
But the Mac partitioner also offers the option to create a PC
compatible partition table, which is what I usually have. In this case,
only sda1 shows up, as usual.

I just added the line 'hfsplus' to /etc/modules.
In /etc/fstab I have:
/dev/sda1 /media/sda1 auto rw,user,noauto 0 0
That's all what is needed to access the HFS+ drive.
Note that there's also the hfsplus package. Without the need for the
hfsplus module, it has commands such as hmount, hcopy etc., and it can
do mac <--> unix text conversion, and conversion from/to MacBin and
BinHex formats.
