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 (andas per message i run "fsck /dev/hda" without any argument/switch.
For your information i have added "fdisk -l" & "df -h" (All outputprior to system CRASH).

If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock iscorrupt, and you might try running e2fsck with an alternatesuperblock:     e2fsck ?b 8193 <device>

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