Replacing a failing hard drive in my TiVo Premiere. It's so far gone that I have to borrow a drive. That means lugging a PC to my Mom's and tearing her Premiere apart and copying her drive to a new one. I have several PCs available for the job. And I don't want to spend 30 hours over there. So, if I take a fast PC (i.e. Core i7, etc.) vs a slow PC (Pentium 4 3.4GHz) will the transfer speed be affected? Also, how long would the copy process take approximately?
