I have a workstation that has been acting up for the last few weeks. It currently has Windows Server 2008 R2 installed on it, and 2 HDD mirrored.
A few times per hour the screen will freeze up, applications will say "not responding", sometimes the screen will turn a lighter shaded color--at the same time the HDD light is on solid. This lasts anywhere from 10 to about 50 seconds.
Could this be something with one of the drives or the mechanism keeping the mirror in place? Any other ideas?
