| The superblock could not be read or does not describe a valid ext2/ext3/ext4 |
| filesystem. If the device is valid and it really contains an ext2/ext3/ext4 |
| 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> |
| or |
| e2fsck -b 32768 <device> |
