Bad magic number in super-block
After a power failure, I can't mount one of my partitions anymore:
e2fsck 1.39 (29-May-2006)
Couldn't find ext2 superblock, trying backup blocks...
fsck.ext3: Bad magic number in super-block while trying to open /dev/sdb1
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
I tried to give the suggested superblock (as well as some other guessed values) as parameter but I get the same error message. With dumpe2fs and tune2fs as well.
Anything I can try to mount the partition again?
