I have a Sony DVD RW DRU-720A. The problem is that when I put a DVD into the drive, it does not recognize that there is a dvd in the drive at all. How should I go about fixing this problem.
Run this update and see if it helps.. If not, get back to me. http://sony.storagesupport.com/dvdrw/downloads/720FWJY08/720A_JY08.zip Make sure when you run it, you aren't running anything else or have a disk in your drive.
