Advertisements OK, I had a series 3 with a WD mydvr expander (I think that's what it's called). I recently upgraded to the new Premiere. I successfully paired my expander with the Premiere but after a few weeks of recording, the Premiere is very sluggish. I wanted to do an internal upgrade because I am pretty sure the slow-down problem is with my external drive. The Premiere was quite speedy when it first arrived and I noticed the sluggishness as soon as I connected the external. Is there any way to backup both the internal and external drives to ONE new internal drive that can be installed into the Premiere? I tried to search but could not find anything. Any help would be appreciated. Think I just found my answer. I must transfer all data to my PC or another Tivo.... Uggh!
