ok i am new to moding xbox's and all and know nothing about the dual harddrives and crap. once i get my mod chip and every thing do i need to use my old harddrive that came with the xbox or can i put a 80 in its place? if so do i need to do anything special to it before i plug it in or do i just put it in and let my modchip boot it up? and how to i make it so i can plug an extra harddrive in? i got the ide cable thats got 2 plugins but i dont have power to my second drive? it there something i can buy to give it power?
