Hello,
I have about 2 years worth of experience with linux, mainly Gentoo, and still consider myself a newbie...
I have been stuck on this problem for a week now, and I have tried so many solutions that I am starting to get lost myself so I'll try to explain as much as I can. Also, this computer's main user is my girlfriend so some info may escape me (although she is not very techie and knows not to mess with things she doesn't know about). First of all : here are my system specs :

What happened : A default Ubuntu 8.10 (installed on hda) was running fine before I decided to clean out the dust from inside the computer (without any of the data backed up, of course... ). At the same time, I figured I would add a couple parts to it, mainly another HDD that I had messed up with Gentoo (hdb) a few years back. When I started up the computer again It worked fine. When my gf got to it, the mouse wasn't working so she decided to reboot.
From this point on, the Ubuntu drive would not boot up, and instead output a Grub 'Error 17' (Filesystem not recognized). So I booted with a Knoppix LiveCD, and tried a couple of things without success.
here is the partition table for hda :
I read that a filesystem check fail could be due to a damaged superblock and that I could use a backup to restore the superblock, which I did without success :Code:root@1[knoppix]# fdisk -l /dev/hda Disk /dev/hda: 40.0 GB, 40020664320 bytes 255 heads, 63 sectors/track, 4865 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hda1 * 1 4660 37431418+ 83 Linux /dev/hda2 4661 4865 1646662+ 5 Extended /dev/hda5 4661 4865 1646631 82 Linux swap / Solaris
'dmesg' spat out a bunch of errors about hda1 that I couldn't decipher :Code:root@0[knoppix]# mkfs.ext3 -n /dev/hda1 mke2fs 1.38 (30-Jun-2005) Filesystem label= OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) 4685824 inodes, 9357854 blocks 467892 blocks (5.00%) reserved for the super user First data block=0 286 block groups 32768 blocks per group, 32768 fragments per group 16384 inodes per group Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 4096000, 7962624 root@0[knoppix]# fsck.ext3 -b 32768 -f -y -C0 /dev/hda1 e2fsck 1.38 (30-Jun-2005) /dev/hda1: Attempt to read block from filesystem resulted in short read while reading block 1289 /dev/hda1: Attempt to read block from filesystem resulted in short read reading journal superblock fsck.ext3: Attempt to read block from filesystem resulted in short read while checking ext3 journal for /dev/hda1
So I figured the whole disk was damaged so I used smartmontools to check for errors on the disk : (I did the short and long test)Code:root@0[knoppix]# dmesg | grep hda1 Buffer I/O error on device

This seems to be contradictory, but I can't really say having never done these tests before ... can someone please help me out ?Code:root@0[knoppix]# smartctl -a /dev/hda smartctl version 5.32 Copyright (C) 2002-4 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF INFORMATION SECTION === Device Model: ST340014A Serial Number: 3JX2ZH3X Firmware Version: 3.06 Device is: In smartctl database [for details use: -P show] ATA Version is: 6 ATA Standard is: ATA/ATAPI-6 T13 1410D revision 2 Local Time is: Tue Mar 31 18:04:12 2009 EST SMART support is: Available - device has SMART capability.
