Hi folks,
I am running redhat linux 9(Kernel 2.4.20-8) server on Intel P4 system,
with Western Digital ATA 40GB Hard Disk(WD400EB-00CPF0, ATA DISK).
This server is acting as Firewall & Gateway.
Running squid & vsftp for local users.
When i power on my system this morning , it shows below message (and
as per message i run "fsck /dev/hda" without any argument/switch.
For your information i have added "fdisk -l" & "df -h" (All output
prior to system CRASH).
Checking root filesystem
/============================= 49%

Inodes that were part of a corrupted orphan linked list found.

(or type Control-D to continue):
(Repair filesystem)1# fsck /dev/hda
fsck 1.32 (09-Nov-2002)
e2fsck 1.32 (09-Nov-2002)
Couldn't find ext2 superblock, trying backup blocks?
Fsck.ext2: Bad magic number in super-block while trying to open /dev/had
The superblock could not be read or does not describe a correct ext2 filesystem.
If the device is valid and it really contains an ext2 filesystem (
and not swap or ufs or something else), then the superblock is
corrupt, and you might try running e2fsck with an alternate
superblock:
e2fsck ?b 8193 <device>
#fdisk ?l

Any suggestion how to recover damaged filesystem (here it's EXT3)?.
Thanks in advance.
