Hi
Hm, ok, let me be the first to reply to you, although I am far not a good specialist in this area, I just hope to provoke somebody to give more professional answers to your problem:-)
1) Try using dd to copy your entire disk to another one (if that's possible), it anyway would be a good starting point, I guess. Smth. like (boot from a floppy, supposing your damaged drive is hda and you copy it to hdb) dd if=/dev/hda of=/dev/hdb 2) ok, now that we have (hopefully) preserved what was possible we can attempt more risky steps: while booted from a floppy do mount -r /dev/hda /mnt and see what's left on your drive... 3) Now you can attempt various fsck's, but be warned - this is where you already CAN make matters worse... First umount umount /dev/hda then smth like e2fsck /dev/hda ...
Good luck Guennadi
P.S. Hey, guys, I know it's a bit off-topic here, but some (all?) of you can help this chap out better than me - please correct what I've said wrong.
