Hey guys, So, my Xbox 360 got banned about a year and a bit ago for having modded firmware. My brother just got a new Xbox. What happens if I sign onto his? I know there is something about HDD's getting crippled... and other things. Basically, what I would love to do is have all my achievements etc, to be there when I sign into XBL. What exactly is going to happen? And what is the deal with crippled HDDs?
