A LiteOn DG-16D2S DVD drive has been found in an Xbox 360 after being repaired by a Microsoft service center in Australia. The drive tray looks just like a BenQ/Phillips drive, so there is currently no external method for identifying systems that have this drive. Currently there is no method for dumping the drive firmware. These drives will most likely begin to appear in newer 360's in the following months.
