So, I'm planing on getting a 250gig hdd, someone else is selling me their old one, and it already has some games on it. I have an 80gig, and the factory hdd in the xbox, I need some help. I have a softmodded xbox by the way. 1: How many hdd's can be in the xbox at once (I paid for my softmod) 2: How do I install a new hdd and play games off of it (do I need to format it?) Thanks for help in advance.
