kel, you do remember that"The Xbox 360 is designed so that the DVD drive works only with the particular game console it is installed in. Replacing a defective DVD drive with a replacement DVD drive does not work, since the replacement has a different DVD drive key, which the game console won't accept." source. Problem is, you can not just change the drive. The drive has to be mated to the console with the right keycode. Check on here and here for more info on this. It is most likely that it does not work is because the drive is not mated...
