now what do I do?

while creating backups my system paniced. i return
to see blinking capslock, scrollock, numlock LEDs.
i reboot.

but cannot boot because my /dev/hda2 mount is unclean.
i use my linux rescue CD. every attempt to run e2fsck
on /dev/hda2 reports: "superblock corrupted" frags per
block wrong.

all attempts on backup superblocks reports: magic number
wrong.

an fdisk -l correctly reports all three partitions.

so i run debugfs (version 1.32) on /dev/hda1. i run
stats command. confirm block size is 1024.

i re-run debugfs. i run command

open /dev/hda2

debugfs crashes with NULL pointer reference problem.

anyway by assumping /dev/hda2 has same blocksize of 1024
i retry e2fsck with every backup superblock known 8193,...
and each one does not work.

now what do I do? what can i do?
