Advertisements I've been a D*sub for many years but started using DirecTivo's about 4+ years ago. I added Weaknees upgrades (extra HD's) to 2 of my Hughes HDVR2's. 3 hard drives failed in 4+ years (out of a possible 4). Anyone else have a similar experience? What is the average life expectancy of a Tivo HD? I say about 2 years? Maybe we can start a poll?
