disk problems or false alarm??



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?
