I've got a WD20EURS on the way for an emergency drive replacement for a 648 series 3, and just want to make sure my understanding of the current upgrade discussion about the 648 model is correct before the new drive arrives. I have a WinMFS backup sourced from a 648 version k 1TB drive, not from an original 250GB drive. Can I do the following to fully prep the new WD20EURS for the installation in the 648? 1. Restore my version k WinMFS backup of the 1TB drive to the WD20EURS (with optimized format and 1024MB swap size) 2. Let it expand when prompted 3. Supersize 4. Install drive in the Tivo and have access to all 318HD HRS Or am I missing something here?
