  1. Boot a live CD, mount your system disk and backup media and hope for the best. If your CD drive is your backup media, then you boot boot from a USB flash drive.

    If your drive is in the process of self destructing, best to mount it read-only.

    google appropriate terms (like "usb boot ubuntu) for specific instructions.

    The next time you install, I highly recommend partitioning your drive between the system and your home directory. That way if the system partition becomes corrupted, you can reinstall w/out touching your existing personal data.

    good luck!

    Hi

    I have tried using ubuntu live cd iam able to boot ..
    but the problem is i have only one partition on hardisk
    when i try to mount the harddrive /dev/sda its not mounting
    its throwing errors
    mount -t ext3 /dev/sda /mnt didnot work .. i tried with many options like ext2,vfat still it didnot work..

    showing wrong fs type. or super badblock etc type of errors ..
    so iam unable to mount to take backup...

    even i tried fsck and e2fsc utilitiles still no use...
    but if i use gpart and make it ext3 it will erase data

    can u suggest how i can specify fs to drive without erasing data on it and after that i vil mount and take backup

    Thnx

    Probably not a good idea to keep trying different file systems.

    Worse yet as fsck will also write to the disk if it thinks it sees a problem it can fix.

    There are techniques to try to recover a corrupted partition but they are beyond my knowledge.

    You never stated how this happened. Describing that might help. You might get more response posting to an Ubuntu forum.

    Sorry I cannot offer more.

    Just type

    mount /dev/sda1 /mnt

    You need to put the 1 there to identify the first partition of your first disk. If you omit the number the system will try to mount from the superblock, and the proper filesystem information won't be there. You don't need to specify the filesystem type for most filesystems. Let it work for you.

    You probably need to reinstall the bootloader. Get your disk mounted and Google to find how to do that.
  5. Hi
