help me save my harddrive

[stellsmi]

So I logged into my debian sarge linux box and was getting error messages where it couldn't write to some mail queue because of the "Read-only Filesystem"

Googling that, I rebooted, in order to run fsck on the device.

I couldn't actually get it to boot, recovery mode or no. So instead I booted a cd of knoppix. So I am know staring at a knoppix xterm trying to use fsck on my harddrive.

I type

fsck /dev/hda0

and I get :

fsck 1.35
e2fsck 1.35
fsck.ext: No such file or directory while trying to open /dev/hda0

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>



anyway, I can't even see /dev/hda0, though I can see /dev/hda, /dev/hda1...

any ideas? I have data on this drive that I can not lose, and yes, I know I should have backed it up.

help?

Do you you have any other operating systems installed on that drive? Do you have any other drives to which you can save the data (can be hard drive, USB drive, or even drive on another computer)?
If you only have Debian installed on that drive, then Debian is probably on /dev/hda1 . If there other partitions on the drive, then partition's number may be something else (/dev/hda#). Knoppix probably has detected all the partitions and displayed them on the Desktop. If not, open the terminal and type:

/sbin/fdisk -l /dev/hda

It should show you what partitions there are on the drive.
See which one is your Debian (Linux) partition.
Before you try to fix the filesystem, backup your data to another drive or computer using Knoppix (the procedure will depend on which other drive you can use). Then try to run fsck on /dev/hda1 (if that's your Debian partition, or substitute 1 with appropriate number).

The 0 is the fault
No device in any linux with name hd*0.
The hda0=hda and only hda exist.
Well use

fsck /dev/hda

if you have two or more partitions on hda use

fsck /dev/hdaN where N=1,2,3,.....

have fun!
