I have 1.19 version. Here is the output of the fsck:

e2fsck /dev/NORAID_HDX/backups
e2fsck 1.19ea, 30-Aug-2000 for EXT2 FS 0.5b, 95/08/09
Group descriptors look bad... trying backup blocks...
e2fsck: Bad magic number in super-block while trying to open
/dev/NORAID_HDX/backups
 
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>
 
[root at fatboy filesrv]#

e2fsck -b 8193 doesn't help...
Any idea?
