Xbox 360 DVD Drive identifying
When having a DVD drive flashed it is sometime helpful to be able to tell which drive unit you have in your Xbox 360 console.

If you havent got a HDMI port on your Xbox360 then you have either a Hitachi Drive or a Toshiba-Samsung Drive. Drive units can be 'spoofed' , so this is only strictly the case if the Xbox has not been flashed.

If you do have an HDMI port, eject the tray and look at the shape, this will let you know whether you have a philips or Hitachi Drive.
Philips BenQ and Philips Lite-On drive units have the same tray. So if you have a philips tray, look at the front of the drive unit.
A Philips Lite on drive has a yellow wire, a Philips BenQ drive has a white wire.
