Hi,
I run hundreds of Redhat 8.0 boxes and Fedora Core 1 boxes, both
Operation systems boxes give me some trouble reporting disk errors like
the following (collected from /var/log/messages of each linux boxes by
my own script). And a "badblocks" command on some of the related hard
drive reports that failed sectors found, while others reports no,
false-positive. Any one can give me suggestions or hints?
Thanks a lot.

...... blahblah...
I tried to run "badblocks" on the boxes to test whether there are real
hardware problems, then I got some of them really reports problems, and
some of them NOT. Anyone know why?
