I have a PS3 Slim 160GB, and I buy quite a few digital games, including PS3 games. Of course, someday I might need a new drive, and that's where my questions come in. 1. Can I use any old modern SATA hard drive in a PS3, or do I need a special kind? 2. Will the old data on a new HD work just as well as the old HD? 3. How hard is it to remove a PS3 Slim's HD? Can I do it myself, or do I need to ask my computer guy?
