HP Lightscribe Ext Int DVD Rewritable Drive Burner R/RW USB DVD-640 5169-0463. External DVD burner. Can be removed from the case and used as an internal drive. Was used to removed files from laptops that did not have a DVD burner in them I did not have a power supply, opened up and figured out the pinouts to connect to a PC power supply. Power wires have been cut from the power supply, can easily attach a new power supply. Drive inside has not been modified Has the USB to IDE drive board inside.
