I know there were several threads on the noisey hard drives a while back but I couldn't locate them. This has been going on for over 2 years now but over the last couple of months has gotten quite annoying. Sometimes the noise over powers the the audio of a show. And sometimes when all are off it gets to be the only thing you can hear in the room. I am not sure if this is happening to all HD DVRs or just the HR20s. Is this D's way of telling me I need to spring for a newer model or is everyone hearing it? I swear if this continues I will simply discontinue the DVR. Oh, one other question, does it go away if an eSata drive is attached? Sorry to be complaining, I know this was beat to death some time ago, but it just is finally getting to me.
