Go buy a 1TB laptop drive and use the computer to copy the data, on mine i have over 50 Xbox 360 games, another 30 original xbox games, 40+ arcade games, and another 1000+ games in all of my emulators(Mame(4025), SNES(2000), nes(all of them except the original zelda

), Sega Genesis), And i still have over 450GB free. The downfall of using an external fat32 drive is you cannot install dlc/arcade/Indie games to it, which is one of the main things people use their xbox for. If it is a demon system i would suggest the dual internal HDD Mod(Unfortunatly I have not been able to implement this on the older style systems(Not enough room in the hdd caddy to mount 2 hdds, I tried, And unfortunatly i dont know any one who does custom plastic work. Would be nice to be able to get as one of the many promised Demon Addons. Hint Hint. lol.) Here is a guide for installing a bigger HDD in a jtag

Also dont forget to install the Hacked xbox compatibility files(For Xbox Original Games)
