It's defiently the Thomson drive if none of the above advice worked out. Every game in my collection function fines with my Thomson except for Halo 2. I've seen some Thomson drives read it perfectly, and some not read it all, so it's really just the luck of the draw depending on which you get. Check out the BST forums here if you're looking to buy a drive, sometimes you can find a nice deal on "new" or "rarely used" drive.
