This little optical drive that I got for under $10 was plug in and worked! I am quite surprised at the quality of this GENERIC USB DVD WRITER. Its compact, fast and perfect for a laptop that had a DVD writer but was ruined by a Cleaning Disc. (ALERT make sure your cleaning discs are FOR LAPTOPS) I am using the burner now to take care of some backed up burns that needed to be done and it is quietly working on the side doing a fantastic job. Came with both power and USB cable plus mini disc with drivers but that was never needed as WIN7 found the drivers needed and it was up and running in 2 minutes flat. TERRIFIC BUY!
