Default Recover exented superblock

I was following http://www.howtoforge.com/linux_resi...xt3_partitions and when i reboot and run:

root@Microknoppix:/home/knoppix# fsck -n /dev/sda7
fsck from util-linux-ng 2.17.2
e2fsck 1.41.12 (17-May-2010)
fsck.ext2: Superblock invalid, trying backup blocks...
fsck.ext2: Bad magic number in super-block while trying to open /dev/sda7

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>



so i ran e2fsck with all the block numbers that you need (forget exactly what tool i used to find where the superblocks are hidden) no dice

then i ran testdisk and had it look for the superblock, no results


anyone have any ideas?


fdisk -l for reference:

root@Microknoppix:/home/knoppix# fdisk -l
