Windows 2003 x64, 3ware 8504LP, 4x200Gb in RAID5. I've seen the following in my event log:

Code:

              All associated busses were reset in an effort to clear the condition.

The earliest timestamp is Mar 09, because I only installed Windows 2003 on this box on Friday. Before that, it was running Ubuntu.

I'm currently restoring my FLAC collection from backup and listening to some MP3s on a different computer, so the disk's getting hammered reasonably hard. Oh, and the music skipped at the time of the last one.

Are these warnings the sign of an impending disk failure? Should I replace the disk on port 3? I've got a couple of spare 200Gb disks banging around here somewhere. Or should I wait until these kinds of things are happening more frequently, and when the computer's not under load (i.e. closer to normal use patterns)?
