short read while checking ext3 journal



My UPS failed and my server took an 'unscheduled outage' a few weeks ago. 
The only casualty appears to be a volume I used for backup.  I usually
maintain data on multiple hard disks, but in this case I errantly had some
data (of marginal value) on this file system.

At this point, the data is not worth enough for me to send the drive out
for data recovery, but it's worth enough to make me want to try to recover
it.

Here's what's happening:
[root marvin root]# mount /dev/hdb1 /backup
mount: wrong fs type, bad option, bad superblock on /dev/hdb1,
       or too many mounted file systems

[root marvin root]# fsck /dev/hdb1
fsck 1.32 (09-Nov-2002)
e2fsck 1.32 (09-Nov-2002)
fsck.ext2: Attempt to read block from filesystem resulted in short read
while checking ext3 journal for /backup

I thought removing the journal might help.  I doubt that the files that
interest me were open at the time.

[root marvin root]# tune2fs -O ^has_journal /dev/hdb1
tune2fs 1.32 (09-Nov-2002)
The needs_recovery flag is set.  Please run e2fsck before clearing
the has_journal flag.


Any ideas?

Thanks!

Tom
