Transferring data to new Xbox 360 Slim
So I have the old original Xbox 360s. Mine overheated and I'm thinking of buying the new 360 Slim. All my data is stored on my old detachable hard drive. I noticed the new Slim has a built in hard drive and the new 250 add on hd is completely different hardware.
How do I transfer my old data on my old hd into the new 360 slim? I don't have any music and heavy stuff on it, only game data. Are all my CoD data for instance actually saved on my hd or is it saved online?
