One used Lite-On IT Corp DVD drive. Model DH-20A4H08C. Used and I could not test. Case shows rust as in photos. This was saved by a friend who saved working computer parts. I have sold many of his hard drive, dvd and cd drives with only one issue. Happy to combine shipping. I have some ribbon cables etc listed that would ship for free with this unit as they would add little weight. If it has an issue we can work it out.
