It is very important IMHO to perform a low level test of<BR>
the disk anytime possible corruption occurs. A sector<BR>
or group of sectors can become marginal. Manufacturers<BR>
of disk drives provide free low level testing software.<BR>
<BR>
I would run the low level test before I tried to fsck the<BR>
drive, it could mask the problem -or- make it worse.<BR>
<BR>
I recommend turning on S.M.A.R.T on your drives and<BR>
running S.M.A.R.T reporting software on your system.<BR>
Many times S.M.A.R.T testing or low level testing will<BR>
let you know if the drive is failing or about to fail and<BR>
if this is the case, then you are wasting your time<BR>
running high level OS file recovery routines suck as<BR>
fsck, chkdsk, drvchk etc.<BR>
<BR>
Know your drive is good before you mess with the data.<BR>

fsck was the first thing I did. It doesn't see anything wrong with the
file system. Guess whatever is the cause is not something that offends
fsck. I did not try bad blocks though. I thought that was for marking
bad blocks on the disk so they were not used at all. Not so?
All I really need to do is delete the now extraneous entry although if it
were it recoverable I think it would be an interesting learning exercise.
