Heard the infamous *click* *click* coming from one of my hard drives. Problem is, I have four internals and three externals, so I have no way of finding out which one was doing the clicking. I ran a diagnostic tool and all seem to check out fine. Any suggestions for isolating the problem? Also, I used the Western Digital diagnostic tool on a Maxtor external, and it didn't like it too much, though it produced an 'ok' result. The Maxtor is the oldest drive so I'm suspicious. Anyone recommend a good diagnostic tool to monitor the hard drives? or a good way of monitoring them so I can be confident they are good to go?
