Mounting a disk using backup superblock [was: Re: My superblock has been destroyed - please help!]
Hello!
Below you see a copy of the last thread I'm referring to. My HDD and
especially the superblock no.1 is heavily demaged - but I now have managed
to e2fsck the partition using the backup superblock number 32768. Debugfs
/dev/hda2 can also show me the contents of the partition, but "mount -t
ext2 -o sb=32768 /dev/hda2 /mnt" just won't mount it and says "bad magic
number" etc. Can anyone please tell me what I'm missing? Does mount
calculate the superblock offset in another way or should I give up or??? I
need this data desperately as I mentioned. If anyone can help me, thanks
thousand times in advance.
Cheers,
Stephan
