when I put a blank disk in my dvd drive It shows the disk as empty. I can go into the drive and see nothing on it. When I hit properties it shows as 0 memory available and 0 room used. I can not then write to the dvd disk. I have tried all the disk formats that are supposed to work on the disk drive. I can not format the disk. It will read a dvd disk or CD and burn a Cd, but I can not burn a Dvd. I can not figure out what settings I need to change to make the Disk work. when I put a blank cd in it It shows all the memory as available like it should. What do I need to reset to write to a DVD?
