Hi, My setup: - Non Slim Xbox 360. I think mine is Jasper. - Latest Dashboard (I play online; so I always have latest). - Genuine 120GB HDD. I have already ordered a new non genuine 250GB hdd from eBay. I see many complaints in the Internet that somehow people screw up the disk. 1. What is a 100% working way not to screw up the disk? 2. Should it work connecting it directly to console? 3. Can I format it in the console? I've seen cases when people report that after format 120GB disk became 20GB disk with 16GB free etc. 4. Maybe I need to backup something from that disk (bin files) so I would be able to recover the bricked disk and start all over. I have the non genuine transfer cable. I can transfer all my save files via USB flash memory. I won't use the transfer cables if that can screw up the disk. Thanks!!!!!
