data recovery

[Javier Govea]

Hi,

The hard disk of my Red Hat installation just crashed by some unknown reason. I'm trying
to recover all data from the hard disk with no luck so far. 

The linux recovery mode upon starting first told me that i don't have any partitions. But
once i'm in the recovery mode i can list my partitions with fdisk -l. I can mount
/dev/hda1 (my boot partition) using mount but it is mounted as ext2 (it should be ext3) I
have access to almost all information in hda1 as an ext2 partition. 

But the information i really want is in /dev/hda2. I cannot mount hda2, not even as ext2.
If i try to mount hda2 as ext3 dmesg shows me this:

hda: read_intr: status=0x59 { DriveReady SeekComplete DataRequest Error }
hda: read_intr: error=0x40 { UncorrectableError }, LBAsect=261192, sector=4152
end_request: I/O error, dev 03:02 (hda), sector 4152
JBD: IO error reading journal superblock
EXT3-fs: error loading journal.

and fsck /dev/hda2 shows me:

fsck 1.32 (09-Nov-2002)
e2fsck 1.32 (09-Nov-2002)
/: Attempt to read block from filesystem resulted in short read while reading block 519
/: 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 /

So, I think I have some damaged blocks. Is there any tool that I can use to recover my
information? or to fix the damaged blocks? will e2fsck -c recover/fix something? i'm not
very familiar with e2fsck, i don't want to run it until i'm completely sure i won't screw
up my hard disk even more.

Any help is very much appreciated.
Thanx a lot
