    Unable to mount external USB WD HD using Knoppix

    Hello Gurus,

    I need urgent help! Here's the story -
    I have a Compaq XP desktop which was working fine until last week. Now, it doesn't boot. It gives the following message:
    --------------------------------------------------------
    1720-SMART hard drive detects imminent failure.
    Your hard disk drive is detecting an imminent failure. To ensure no data loss, backup contents and replace this hard disk.
    Attribute Failed: # 05
    --------------------------------------------------------

    On trying to boot it complains about missing system files.

    At first, I thought that my hard drive is fried. But then I am able to access/view all my precious data using Knoppix (using CD)!!
    So, I have a following plan to recover the data (and PC):
    1. Copy all the data to an external drive. (I bought one Western Digital dual-option USB 2.0 hard drive 80 GB. It is preformatted to a single FAT32 partition).
    2. Restore the XP to factory default using the recovery CD.
    3. Reload the data into the hard disk from the external hard drive.

    I believe my hard drive is fine, just the XP (boot/system files) is corrupted. Is that true?
    Nevertheless, I am stuck at the Step 1 above. As soon as I plug in the external HD, Knoppix just freezes. The same thing happens when I try to boot Knoppix with the HD plugged in.
    I am really a first time Knoppix user. I looked at the forum tried options that I could understand. Here are some details (A through H) that may help you help me!

    A) fdisk -l

    Disk /dev/hda: 80.0 GB, 80026361856 bytes
    240 heads, 63 sectors/track, 10337 cylinders
    Units = cylinders of 15120 * 512 = 7741440 bytes

    Device Boot Start End Blocks Id
    System
    /dev/hda1 * 1 9796 74057728+ 7
    HPFS/NTFS
    /dev/hda2 9797 10337 4089960 f
    Win95 Ext'd (LBA)
    /dev/hda5 9797 10337 4089928+ b
    Win95 FAT32

    B) cat /etc/fstab

    proc /proc proc defaults 0 0
    pts /dev/pts devpts mode=0622 0 0
    /dev/fd0 /mnt/auto/floppy auto
    user,noauto,exec,umask=000 0 0
    /dev/cdrom /mnt/auto/cdrom auto user,noauto,exec,ro
    0 0
    /dev/cdrom1 /mnt/auto/cdrom1 auto
    users,noauto,exec,ro 0 0
    # Added by KNOPPIX
    /dev/hda1 /mnt/hda1 ntfs noauto,users,exec,ro,uid=knoppix,gid=knoppix 0 0
    # Added by KNOPPIX
    /dev/hda5 /mnt/hda5 vfat noauto,users,exec,umask=000,uid=knoppix,gid=knoppi x 0 0

    C) cat /proc/partitions
    major minor #blocks name

    3 0 78150744 hda
    3 1 74057728 hda1
    3 2 1 hda2
    3 5 4089928 hda5

    D) lsmod |grep usb
    usb-storage 54524 0 (unused)
    usbmouse 1788 0 (unused)
    usbkbd 2876 0 (unused)
    input 3200 0 [mousedev keybdev
    usbmouse hid usbkbd]
    usb-uhci 21868 0 (unused)
    usbcore 57120 1 [usb-storage
    usbmouse hid usbkbd usb-uhci

    E) mount -t vfat /dev/hda /mnt/usbhdd
    mount: wrong fs type, bad option, bad superblock on /dev/hda,
    or too many mounted file systems

    F) root@ttyp0[knoppix]# mount -t fat32 /dev/hda /mnt/usbhdd
    mount: fs type fat32 not supported by kernel

    G) root@ttyp0[knoppix]# mount -t auto /dev/hda /mnt/usbhdd
    mount: you must specify the filesystem type

    H) root@ttyp0[knoppix]# mount -t vfat /dev/sda /mnt/usbhdd
    mount: /dev/sda is not a valid block device


    FYI, I am runnig Knoppix using a CD.
    Can anyone please tell me how can I achieve what I am trying to do?
    Again, this is very first time I am trying to use knoppix. I may need detailed Instructions compatible to a novice.
    Greatly appreciate your help!

    Thanks,
    Vinay

    If SMART says your drive is about to fail,it is.Get another hard drive.
    I've never had knoppix lockup when plugging in a usb device.
    Sounds like an irq conflict.You should look through the dmesg output and
    /proc/interrupts.Look through the cheatcodes on the cd and try
    some of them.
    To mount a usb drive try
    mount /dev/sda1 /mnt/test
    Compaqs have been known to have a screwed up bios.
    They also use the cheapest components they can get away with.
    If you can't get your usb drive to work,I suggest either backup to
    another hard drive(slave) or try backing up over your lan to a
    windows share on another pc.
    Good Luck
