I’m having a bit of a noise problem… running a fanless system (Zalman TNN-500AF case) and have two 500GB Blues running in it for years with no issues. I just bought this WD30EZRS and there’s an odd 2200Hz pure tone whine that is very directional (tilt your head or stand in a different part of the room and it disappears). I have tried three of these drives and they all exhibit it (first two from new egg were sub model 00J99B0 and the one from WDC directly that I have now is sub model 11J99B0).
Is this a design issue? Number of platters? Bearing type that is different from my WD5000AAKS? Is there a solution that doesn’t involve me having to return it and give up a 15% restocking fee only to gamble on another brand or model drive?
