I just got a Motorola DCT6412 combo HD/DVR box from Comcast, and I'm hearing a noise I didn't expect from it. It's much like a hamster running in a hamster wheel or a fan that is slightly out of balance( i.e. the noise isn't completely smooth). It kind of sounds like "chika-chika-chika". I can hear it from my couch 10 feet away, though I do have a quiet room and a good pair of ears, heh. Now I know the hard drive is running all the time (and the sound seems to be coming right from it), but from all the computers I've built I've never heard such a noisy drive. If I did, I'd assume the drive was a super cheap one or that it was about to fail on me.
BTW, the box seems to record and function normally. The one odd thing I see is that if I shut off the box (which causes the noise to stop), the red record light comes on even though I have nothing scheduled to record.
Any similar experiences out there? Is this sound normal for a DVR?
