It's the "silent" model with the "Hydrodynamic Bearing motor technology". The high pitched whine it emits is seriously driving me crazy. I can't hear it when I'm at the computer right next to it, but when I go to the next room to sleep it's loud and clear. So loud I CANNOT SLEEP. Now I either wear ear plugs or shut down the computer and disconnect the drive.
This sucks. I guess there's nothing one can do about it? Have to start looking for replacement... any suggestions for a fast non-whiny(!!!!!) 80+ gig drive?
