Likely, although volume errors like this can also be soft errors on a good HDD 
where the volume got messed up by something else. Check the SMART status, and 
make sure you have good backups, but this isn’t a definitive signal the drive 
is failing. Two such errors in a short time is, though.

Much fun indeed. The best come from old server-grade SCSI drives, they’re 
enormously strong. Our household ‘cookbook’ is about a 30-page stack of recipe 
printouts on letter sized paper stuck to the side of the fridge with one. You 
do NOT want to get it stuck on the fridge by itself, there’s no way to get it 
off except by sliding it to an edge. 

Once I accidentally let two of them come together from too far away, they 
shattered when they hit each other. Very sharp, glasslike shards of magnet.

My Reply @ W.Adrian:

Good advice!

The wayward drive is not the original Sawtooth drive but is at least five years 
old. I plan to replace the Sawtooth with a dual 1.25 MHz MDD which is being 
replaced with a dual 2.5 GHz G5 in the next week or two. The MDD has drives 2-3 
years old. I tend to follow the Mac hand-me-down procedure   --  lot'sa good 
old Mac's out there.

I found an article on Mac OS X hints
http://hints.macworld.com/article.php?story=20070204093925888
that said I could repair the problem by going into Terminal. No go, but is was 
fun getting Terminal commands again. A simple erase and restore solved problem 
with no data loss. KEEP CURRENT BACKUPS!!!

I will run SMART. The other two volumes seem OK but who knows? At least all had 
a redundant back up today.

Magnets -- always wanted to try that. Thanks all --glen
