I don't know if you need a working disc drive but probably not. you won't be using it.

afaik, it's solderless, so it probably just intercepts the sata connection like the blaster did. the blaster was a way to flash the system without opening up the system. ironically, you had to open up the system to install it. it used two boards, both solderless.
Ok. This looks interesting. It works with an official Xbox 360 hard drive or do I need to get a usb hard drive/flash drive?
