Hi, I was wondering what people's experiences with the RH-1, and what it sounds like when functioning normally. My unit seems to be reasonably quiet when recording, but when trying to access a 80-minute, Hi-MD formatted disc via USB, it seems vary, from fairly quiet and slightly buzzy, to louder and almost rattly. It doesn't seem to be as noisy when accessing a 1 GB Hi-MD disc. What's your experiences with this? When should I be worried? I'll try post audio samples of it soon. Thanks, Evan
