Emergency - file system corrupt

[gabriel_007]

Hello
I can't boot my system (Debian Sarge) because of a file system corruption. It says, that I have to do it manually. I launched the mepis live CD, and this is what a utility for checking hard drives said:

Checking/repairing filesystem (e2fsck) on /dev/sda1.
/sbin/e2fsck
: 
Bad magic number in super-block
 
while trying to open /dev/sda1
 

/dev/sda1: 

The 
super
block
 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 
super
block

is corrupt, and you might try running e2fsck with an alternate 
super
block
:
    e2fsck -b 
8193
 <
device
>


Check completed.

Thanks, problem sovled
hardware is to blame - bad RAM. A friend of mine suggested testing this and it turned out that I have bad memory. Debian still seems to be indestructible
Thx

I have the same problem.
It says:

fsck failed. Please repair manually and reboot. Please note that the root file system is currently mounted read-only. To remount it read-write:

# mount -n -o remount,rw /

I typed that and then I've runed reiserfsck and then it says that the partition permissions are set to read-only.

How to change my partition permissions to read-write???

I have reiserfs file system. It's on /dev/hda8

Help, please!

P.S. Sorry for my bad English.

post the output of the following command

ls -l /dev/hda8

post the output of the following command

ls -l /dev/hda8

Here's the output:

brw-rw---- 1 root disk 3, 8 Feb 26 2005 /dev/hda8

1. Boot to single user mode (maintenance mode) and give root pasword.
2. Manually run fsck -y.
3. Remount the file system as read/write (mount -n -o remount,rw /).
4. Reboot the system to run level 2.

It may want to do an automatic fsck on reboot. That's fine if it does.

Hope this helps.

Thanks for help! I tryed this and fixed filesystem, but now I have another problem.

It says:

chroot: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory
Kernel panic: Attempted to kill init!

Does anybody know how to fix this? Could I boot Knoppix and manually copy this library on the linux partition on my hard disk?

I tried to copy libc.so.6 manually with Knoppix, but without success.
Now I've installed Ubuntu. Hopefully there will be nothing wrong with that distro.
