So i reticently purchased a slim from the jungles of Amazon. Used and without a HDD (im giving the seller bad marks for that), I am forced to use a jump drive for now. Its a 16 gig PNY drive. It formats and works... the problem is that it works every time. By that i mean i have to go through downloading updates and my gamer profile EVERY TIME I TURN OFF THE XBOX. So clearly using a USB drive as a HDD isnt a good idea, unless im doing something wrong. In the mean time, im working on getting ahold of a screw driver to connect my old phat HDD as my slim one. Its only 12gigs but it will do right? You can connect a phat HDD to a slim if you take it out of the case right?
