Xbox 360 consoles have internal motherboards that can be hacked to run the JTAG interface. JTAG software enables your Xbox 360 to run custom programs and games from local hard drives rather than DVD discs. You can connect an external USB hard drive to any Xbox 360 via one of several USB ports located on the front and rear of the system. No additional software is required to use an external USB hard drive with the Xbox 360.

Choose "Portable Device" and select "Format Device" by pressing the "A" button. Your USB hard drive will be formatted for use with the Xbox 360.
