Ok here is the deal. I have X3 with 3108 bios. A 1.6b Xbox with an orignal Samsung DVD-ROM and a Western Digital 320 GB hard drive. When I had my 200 GB HD Crash Twinsanity worked fine from my hard drive or a backup multi-game disc. Now that I have upgraded to the new hd this game will not work. I have the hard drive locked and tried disabling my x3 and the original disc still locks up loading the retail bios. This game is my 3 yr old sons favorite game so I really want to figure this out. I have formated the C:\ and E:\ drives and put the MSDash back on the C:\drive. I have cleared all the cache drives in the X3 bios menu and manually via ftp. Any ideas on what the problem could be? I am also using componet cables and HDTV but it worked fine on that before and I also tried using the standard A/V cables with no luck. I can't think of anything else to try.
