I have been seeing periodic errors in my logwatch files for several months. I have been troubleshooting, here is an example:

I have done several things to try to fix/check these. The server is a Dell PowerEdge T610 with PERC 6 RAID controller. With a pair of 1TB mirrored drives. Following Dell support I booted from the installation DVD to the “rescue installation”. I ran FSCK and checked the drive. It found several errors and fixed them. The machine will run for weeks with no other issues. But sometime later some errors will pop up. The next thing that they suggested to figure out which disk might be bad, I booted to Dell’s BIOS utility to perform hardware diagnostics. Ran all the HDD tests on both drives, tested the beginning, end and the rest of the drive. It also passed S.M.A.R.T. test, Buffer test, and drive self test. I expected to find a bad spot on the drive and I have one to swap it out with, but that wasn’t the case. What would be the next thing to try to make sure that I have good drives?
I tried some of the smartctl information:
#smartctl -a returns:

Any assistance would be greatly appreciated. Thank you.
