23 Hi Wol,
24
25 thank you for the link! I have installed mdadm (its on portage) but I

27 tried first.

29 Andrea posted this wonderful line:
30
31 mount -o ro,offset=512 /dev/sdb /mnt/xxx
32
33 which mounts the filesystem by skipping the partitiontable completly.
34
35 Currently I am rescueing the data. If all is safed, I will tru
36 mdadm...
37
38 Thank you very much for your help!
