Can't mount HFSPlus HDD

Hi Folks,

first of all:
Dockstar - Squeeze installed, upgraded to Wheezy (very slow 8GB USB-Stick w/o Swap) - installed hfsplus, -progs, -tools - also installed usbmount.
A 500 GB HFSPlus-HDD (and a 3TB ext4 HDD) worked automounted with r/w.

Now I wanted to use a 3TB Intenso USB 3.0 HDD. Original I had created a 2 TB HFS+ (named "Backups und Daten") and a 1TB NTFS partition on this device under OSX (10.7.5). Afterwards I deleted the NTFS partition and increased the HFS+ partition to 3 TB (named "Daten", now) under OSX without any dataloss. It's nearly full, now. The device was checked and properly unmounted.

Connected to the Dockstar, the device wasn't (auto)mounted.


Tried to manually mount the HDD:

root@dockstar:/media# mount -t hfsplus -o force,rw /dev/sdb1 /media/disk3
mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

What's wrong?

root@dockstar:/media# dmesg | tail

Tried parted:

root@dockstar:~# parted -s /dev/sdb unit s print

 2      51206s  732304496s  732253291s               Backups und Daten

As you can see, parted doesn't show a filesystem on sdb2, but (re-)connected to a mac everything seems to be fine (instead OSX doesn't show the sdb1 partition and shows partition 2 as "Daten").

What am I doing wrong? :-(

Kind regards

Hmmm, after all debian recognized hfsplus?

Edit 2:
Connected to Edubuntu (x86) the system mounts the HDD immediately. I'm driving nuts.... :(
