The JFS drive is made up of a combination of two, smaller, hardware 
RAIDs.  The underlying hardware is reporting no drive failuires in 
either RAID, so I have no reason to believe that the problem is due to a 
faulty drive.  The data corruption followed an unexpected power outage, 
so I'm thinking that's the cause.

I just don't want to have to reformat the filesystem and lose all of my 
data if it's possible to repair it.  (Hence my headaches with jfs_fsck.)
