Alright I'll try to keep this as short as possible... I bought an Xbox 360 in Taiwan when I lived in China and it was, of course, modded. I want very much to be able to play some games on Xbox Live, but I can't with the current Xbox, so I want to buy one that I *can* play online. I was told (at Best Buy) that I wouldn't need to buy an entirely new system, just a hard drive. He said I'd be able to switch out between the hard drive that can play back ups to the hard drive that plays legitimate games, using the same system but different hard drives. My first question: Is this possible? From what I've read on these forums, it doesn't seem like it. It seems like the flashing happens on the xbox's Dvd drive, not the HD. If I can't do this, is it possible to simply use the HD from my modded xbox on my new unmodded one? I'd hate to buy the $349 model since I already have a hard drive. Sorry for the complexity, but I really couldn't find the answer anywhere. Thanks for any help!
