I was able to mount the partition I needed, and accessing some  
subdirectories was no problem at all.  But others, including the top  
level directory, would generate lots of errors.  I was able to copy  
(using scp) some critical files I needed.  I'm still not convinced  
that the disk suffered a HW failure (I'm running the a long SMART  
test now).  How can I determine if indeed the disk failed, as opposed  
to the file system just getting corrupted?  I've salvaged everything  
I need off of this disk, so running fsck on it is not a problem.  I  
would like to determine the root cause, though.
