I have got a new 500 Gig Sata HDD, and am using a Hard drive case from my 20 gig 360 drive, But how do I format it so my 360 will recognize it? This is on a Jtagged xbox. Any help will be appreciated. EDIT: So I figured out that I need a 12v power supply as I am using a 3.5" drive. Where would be the best place to draw that from?
