Trying to recover Linux Partition

[butch81385]

So I had a WD My Book World 1tb NAS drive. One day it isn't working (doesn't even connect to the router). I am trying to recover data from it by putting it into a desktop and using a ubuntu live cd.

Disk utility shows the drive, but says unknown for file system and partition type.
Mounting fails ("wrong fs, bad superblock, or other error") for any type of file system i try.
mdadm says that it can't find any raid array (some drive apparently are set up for raid to connect multiple drives together)
fdisk -l does nothing
sfdisk -l comes up with input/output errors
dumpe2fs gave the response "couldn't find file system superblock"
dmesg | grep "[sh]da" gave a bunch of errors with "i/o error" "Unhandled error code" and "DID_BAD_TARGET"
Just ran Photorec for both ext2/ext3 and for "other filesystems" and both returned 0 files found.


Anything else to try before i call that data gone forever? This was my backup, and it appears to have died around the same time my laptop did.

Tried running the dos program HDAT2 today and it gave me "ERROR reading of the IDENTIFY DEVICE data ata error FFH: Media error/time limit out".

Guessing it's toast...

Tried running DBAN (Derik's Boot and Nuke) and it won't even zero the hard drive due to bad sectors.....
