Hello, I want to buy a modchip for my XBox. All I want to do is backup my games and store them on my hard drive. I have quite a few games so to store them all I am going to buy I bigger hard drive. So, here are my questions: 1. When you are storing games on the hard drive can you still save your progress on the hardrive. 2. Can someone post a link to a guide to replacing the hard drive. 3. Which modchip should I go with? I found this site which documents and compares many modchips http://www.xbox-scene.com/modchips.php I would be interested in knowing what you have and reccomend. Thank you.
