I have the Tivo HD unit, not XL. I am going to put a bigger hard drive in it, 1 tb. I am on other threads about how to do it so I don't have a problem there. The problem is finding the right hard drive. I have been reading about the counterfeit drives coming out of China. Now I hear all the drives are made in China. What is considered a good 1tb drive for the Tivo? What does the forum recommend? Thanks. All ideas are appreciated.
