<What brand and model 1TB are you planning on using? > WD10EADS-65M2B0. Its in a computer now and seems to increment its idle count every 5 min. So hopefully I wont need wdidle3. I'm having trouble booting wdidle3 on my x64 system. I do hardware design for a living, so none of this is tough in that regard. Just getting all my ducks in a row before starting. The symptoms I'm having are strange. I get long pauses. Yesterday it recorded the Daily Show and then said there was no signal when I tried to play it. It recorded another show at the same time and it played fine. I looked at cable signal strength and it was 100. I re-seated all the rf connectors anyway. Maybe it is reacting to some weird Comcast issues? I want to up the drive anyway, so this is a good excuse to get it done.
