Strange Noises

[PiKe]

One of the hard drives in my system (Can't identify which) is making unusual noises, sounds like the head recalibrating or something like that, all the drives are western digital, is there a utility I can run to find out which one is on it's way out? S.M.A.R.T status isn't reporting anything odd...

Depending on the case, take them out and put a screwdriver on them and listen for the noise down the screw driver. I recently did this with one of my Seagates
