mounting a mac os drive in opensuse

[George Olson]

I am trying to mount a mac os drive (from my son's broken mac) into
linux to get the data off of it. I actually successfully did this with
the same drive about 6 months ago when I was using 11.4.

I installed hfsutils, used fdisk to check which device the drive is when
I plugged it in, and it is /dev/sda1. So I made the directory
/mnt/macdrive and then as root typed the following with the following
result:

linux-aw90:/ # mount -t hfsplus /dev/sda1 /mnt/macdrive
mount: wrong fs type, bad option, bad superblock on /dev/sda1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

so I checked dmesg | tail and I get this for the last couple of lines:

[ 874.947485] hfs: unable to find HFS+ superblock
[ 899.247767] SFW2-INext-DROP-DEFLT IN=eth0 OUT=
MAC=48:5b:39:f3:76:92:c0:3f:0e:7e:fa:f9:08:00 SRC=192.168.0.1
DST=192.168.0.151 LEN=78 TOS=0x00 PREC=0x00 TTL=64 ID=398 DF PROTO=UDP
SPT=1025 DPT=137 LEN=58

I don't follow that last line except that I see a mac address, my
default gateway, and my ip address. Don't understand the other things.

So I was thinking that maybe it is hfs and not hfs+, so I tried to mount
it as hfs instead:

linux-aw90:/ # mount -t hfs /dev/sda1 /mnt/macdrive
mount: wrong fs type, bad option, bad superblock on /dev/sda1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

same result. Any ideas?

Try mounting without specifying the filesystem type. Linux is usually
smart enough to figure it were as we mere mortals sometimes get it wrong.

I did that, and it mounted. Thanks! Weird thing was, the mac drive
actually has 2 partitions, and I finally figured out using yast expert
partitioner that it was sda2 that I need to mount for the data. The
partition table is of type GPT, and there is a warning that says fdisk
doesn't support GPT. I guess that is why fdisk would not show the entire
partition table for this drive. It only showed /dev/sda1, and /dev/sda2
wasn't even listed.

the reason #mount -t hfsplus /dev/sda1 /mnt/macdrive didn't work was
because /dev/sda1 is some kind of mac boot partition format and is not hfs+.

You are correct. The first partition is an EFI Boot partition and it is
actually FAT formatted. Parted does support GUID partitions and would
show all of the partitions. This is likely what YaST is using in the
backend anyway.

For future reference, the second line you received when checking dmesg
