My grandaughter has a ToshibaSatellite laptop M115 –S1061 with Windows XP home edition and she broke the tray on the CD/DVD drive.
The broken drive was Panasonic model UJDA770 . I ordered a new UJDA770 and installed it. It spins and seems to be doing something, but it doesn't show up on the "my computer" screen. I figured if i got the same model there wouldn't be any problem with the software, but if I knew what I was doing I wouldn't have to ask for help.
