How to rebuild a damaged ext3 superblock?
My fedora core 3 system recently got stuck and so I had to do a hard reset of my computer.
When booting up the next time, the system tells me that it is unable to read the superblock information.
Knoppix helped me to at least boot up a linux.
This is my current situation:
fsck and e2fsck both resign to work with a corrupted superbock and don't accept my specification of the backup superblocks (using the "-b" argument)
Only dumpe2fs was helpful. This is its output:

Any suggestions of how to recover my hda7?
Thanks in Advance.
