Can I take a hard drive from a 40 hour Tivo Series 2 and place it into a Humax T800? My lifetime Himax drive died. I have a 40 hr Tivo that is not being used. Is spending $150 for a 300GB drive from Weaknees my only option? I'd just like to replace an 80 GB drive with something comparable as my TivoHD is my main box anyhow.
