I just bought Battlefield 3 today, but I had to make my Hitachi 79 I bought run as a Hitachi 47 as I did not know if it would work or not, and it is flashed with LT+1.9. I put the game in and it loads until my Xbox goes dark and blinks with one red light. I then try to turn the Xbox WITH the game in, and I get a pop up saying it's a system error E66. However, when I play any game like Battlefield 2, Halo Reach, Rock Band 3, etc. It loads up and boots just fine, no problems at all even on Xbox Live. Do I need to reflash my Drive to stock, or what? I don't have the money to buy another Hitachi drive.
