Hi, guys...this is my first official post. I have a modded 1.1 with a xenium chip and on its bios thay have a sweet utility to upgrade hd's or ghost, whatever. Anyway, I upgraded the drive just fine and everything looks exactly the same as the old one, even all my soft mods like evox dashboard and all. The problem im have is the now games like burnout 3, battlefront and some other games lock up when there booting. If i plug my old hd in they boot up fine. Dont get it guys, ive tried two different hard drives (250, 20 gigs) both WD and same problem. Plug it back to my original....they boot up fine...please help, thanks in adavance.
