Advertisements Ever since updating to the new 20.2 software, one of my TiVo Premieres is always really loud. The other is whisper-quiet. It's not a fan noise but more like computer noises. It sounds kinda like a hard drive constantly reading and reading, but loud. When the TV is muted or quiet, it's noticeable. Four things I know: This wasn't a problem before I upgraded to 20.2. It isn't the fan. I know what the fan noise sounds like. It isn't happening to my other TiVo, which also has 20.2. It's silent except for a very faint fan noise. The only difference between the loud one and the quiet one is that the loud one is attached to a 1 TB external hard drive. Any thoughts? Could it still be processing the update or guide data? How can I make it stop!?
