Some time ago I had a similar problem with an external WD Scorpio Blue disk.
As my point of view, it tends to park its heads too often, even under
so this results in a clicking.
As far as I remember, you can check Load_Cycle_Count from SMART output.
Take some measurements during minute or two. Rapid growth of this parameter
indicates a problem.
