Do you occasionally hear a higher then usual seek like noise/drone when sitting in silence? I've noticed this a few times today while sitting here in silence. It sounds a bit alarming, the drives run great and all, but I don't know. Sounds suspicious, you know? Just wondering if anyone else has heard this before. Maybe I'm just not used to it. To describe it a bit better, it's louder then the normal seek noise and lasts longer. Maybe 2-3 seconds, BRRZZZZZZZZ, then it stops. It may very well be normal, some kind of adjustment of the seek handle or what not - I'm not sure. It sounds like a vibration noise, but it's not.
