damaged partition

[Markus Feldmann]

Hi All,

since weeks i cant access the laptop from my girl-friend. This laptop
has a dual boot system (Windows and Debian Lenny). When i try to start
the Linux System he stops at a specific point, where he cant find some
devices under /dev/. Further i tried to boot a live-CD and mount the
Linux System manualy without success.

My partition-table is:
     Disk /dev/sda: 80.0 GB, 80026361856 bytes
     255 heads, 63 sectors/track, 9729 cylinders
     Units = cylinders of 16065 * 512 = 8225280 bytes
     Sector size (logical/physical): 512 bytes / 512 bytes
     I/O size (minimum/optimal): 512 bytes / 512 bytes
     Disk identifier: 0xb1c0b1c0

        Device Boot      Start         End      Blocks   Id  System
     /dev/sda1   *           1        8032    64517008+   7  HPFS/NTFS
     /dev/sda2            8415        9728    10554705    f  W95 Ext'd (LBA)
     /dev/sda3            8033        8414     3068415    c  W95 FAT32 (LBA)
     /dev/sda5   *        8415        8420       48163+  83  Linux
     /dev/sda6            8421        8547     1020096   82  Linux swap
/ Solaris
     /dev/sda7            8548        9728     9486351   83  Linux

     Partition table entries are not in disk order

Here are some further tests:
<fsck /dev/sda7>
     fsck from util-linux-ng 2.17.2
     e2fsck 1.41.12 (17-May-2010)
     /dev/sda7: clean, 232529/1186688 files, 2143683/2371587 blocks

<mount /dev/sda7 /mnt/sda7>
     mount: Stale NFS file handle

<fsck -b 32768 /dev/sda7>
     fsck from util-linux-ng 2.17.2
     e2fsck 1.41.12 (17-May-2010)
     fsck.ext2: Bad magic number in super-block while trying to open
/dev/sda7

     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>

I tried all backup-superblocks without success.

<file -s /dev/sda7>
/dev/sda7: Linux rev 1.0 ext2 filesystem data,
UUID=96380d35-74fd-4c37-abc9-9dfc3d1bd43e

<blkid | grep sda7>
/dev/sda7: UUID="96380d35-74fd-4c37-abc9-9dfc3d1bd43e" TYPE="ext2"

<fsck.ext2 /dev/sda7>
e2fsck 1.41.12 (17-May-2010)
/dev/sda7: clean, 232529/1186688 files, 2143683/2371587 blocks

<mount -t ext2 -o ro /dev/sda7 /mnt/sda7>
mount: Stale NFS file handle

I only need the data under .thunderbird/, but i need to mount the ext
partition first? or not? Is there another way to get my data?
