Unhappy Superblock could not be read


I'm havin a P4 1.8Ghz, 256 ram pc with rh9 installed with win98se.
i've installed linux around 2 months back. i was not facing any problem booting into linux until today.
today when i selected linux in my grub loader, after the initial screens linux gave me this eror.

superblock could not be read or does not describe a correct ext2 filesystem. if device is valid and contains an ext2 filesystem then superblock is corrupt & try running e2fsck with alternate superblock. e2fsck -b 8193 <device> fsck.ext3- no such file or directory while trying to open \LABEL=/

then it asks me for a root password, which when i give, prompts me to a 'repair filesystem' prompt.
the command specified in the error does not work. when i press ctrl+d the system reboots.
tried all posible options.

thanks in advance.

try the redhat cdrom rescue mode and see if you can fsck or mount the
drive.

the mandrake should work fine. boot in rescue mode
with the first mandrake disk and see if you can mount or
fsck your linux partition with it.

is there anything important on the drive?

i don't know the commands to try to mount a partition with an alternate superblock.
i'm sure there's some recovery howto around on the web or this site, but i haven't had
to read it so i don't know. there's a good chance your linux install is all messed up.

Right now Im on windoze at school. But if you do a mkfs.ext3 --help or a man mkfs.ext3 you should find something about using a different superblock. I'll look tonight and have it tommorrow (my stupid laptop has a damn winmodem)

first umount the drive then su after that do a fsck.ext3 -c /dev/device OR fsck.ext2 -c /dev/device and it should output the badblocks. If your superblock is really bad then the first bad block should be that which your superblock is on. so do a fsck.ext3 -b newsuperblock OR fsck.ext2 -b newsuperblock where newsuperblock is not on of the blocks output from the latter command
