These errors indicate a read error on the device, I think.

Try running "e2fsck -b 32768" or "e2fsck -b 98304".  It may be that
e2fsck 1.26 already checks all of the possible backup block groups for
you, but I don't know what version that was added in.

You should also try whether "dd if=/dev/hda9" works at all, since it
seems you have some pretty major problems.
