This is an OEM Toshiba Samsung TS-H943A disc drive for the original Microsoft Xbox 360 "fat". This disc drive has been thoroughly cleaned and all moving parts have been lubed. Fully tested and guaranteed to work as it should. Please verify that the Xbox you are purchasing this for has the exact same model disc drive because you will have to install the original DVD logic board PCB and they are not interchangable between different models. Ships with USPS ground advantage.
