Up for sale here is a replacement disc drive for the Xbox 360 slim console. This is the DG-16D4S model of the drive. This DOES NOT include the internal drive PCB, this is not included because you must install the PCB from your old drive into this new one. If you do not, the drive will only play DVD movie discs and not games. This will require soldering to get the PCB installed. NO RETURNS OR REFUNDS for not understanding how the process works!
