Recover Corrupted Partition from a Bad Superblock

Many times a filesystem check fails returning with the error message “Damaged Superblock”. This article will help you in recovering the corrupted partition due to damaged superblock.

Backups of the superblock located on several positions from where we can restore them. Backup locations are: 8193, 32768, 98304, 163840, 229376 and 294912.

Suppose you get a ¨Damaged Superblock¨ error message at filesystem check and you get a root-prompt in a recovery console, then you give the command:

# e2fsck -b 32768 /dev/sdax

System will then check the filesystem with the information stored in that backup superblock and if the check was successful it will restore the backup to position 0.
