I'm seeing all these threads about hard drives and external power and blah blah blah and its confusing my small pea brained head. Okay, I want to hook up an external hard drive to my 722. With that being said the drive I have is a 120 gb laptop drive that I made an external with an external casing. How do I hook up a dedicated power supply to that? It won't just work if I plug it into the reciever's usb port? It did come up with the weirdest damn usb cable ive ever seen. Its got the end that plugs into the drive and then its got two usb ends coming out of it. Its got a short wire with a usb end on it and a longer wire with a usb end on it. Is that how I hook it up to a power source like a powered hub? One end in the hub and the other in the reciever? Would that work? Also, the only hub I personally have is the one that came with the original rock band game. lol Its a four port usb hub that plugs into one usb port making it four ports, but it does plug into the wall for power. Would that work? Man I'm confused...lol
