My HR20-100 has become very noisy. I am not sure if it is the fan or the disk. I have rebooted and left it unplugged but the sound comes back every time. I think it might be time to get a replacement, but I do not want to loose the hours of shows I have not watched yet. I do not think there is a way to save my shows, but I figured if there was, someone here would know. So am I out of luck?
