Broken e2fs...please hellp

["Dean A. Roman" <droman@chattycow.com>]

Hello all,
   It appears that the superblock is bad?  I have tried some other superblocks
with no luck.   The following commands below show the problem.  I can't mount
the file system either.  I checked the partition table with fdisk and everything
looks fine...except the partition no longer lists the file system as a "linux
ext2" description, but a "linux" description.

Any ideas?  I must to get info. off this file system.



I'v also tried 8139 and others.
grumpy:~# e2fsck -b 16386 /dev/sdc1

e2fsck 1.18, 11-Nov-1999 for EXT2 FS 0.5b, 95/08/09
e2fsck: Bad magic number in super-block while trying to open /dev/sdc1

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>
