Re: THIS IS DRIVING ME BONKERS
do the fans spin up inside the xbox when you turn it on, also did you ground your xbox case to your computer case when you were powering the drive, all the tuts tell you to but the majority of people dont, although its fine in most cases you can power surge your xbox if its not grounded, a friend of mine has this happen a while back but not like what your having, his would just eject the drive as soon as it was connected, was deffiatly a problem with the motherboard as the drive was totally fine, if the fans spin up try another drive in your console and see if it will play dvds as it obviously wont play games without the drive key off your 9 series liteon
