My DVD drive was working fine when I first got the system a couple of weeks ago, but now all of a sudden my drive doesn't work. Its a SH-22AB. It opens and closes no problem, but won't recognize any discs. It shows up in the device manager as working properly, but doesn't even show up as a drive in windows explorer. I checked for a driver update, and I didn't even see a driver for windows 7. When a disc is inserted, it makes a a quiet and quick weird noise like a mechanical failure. I'm guessing I just need to go get a new drive, but I thought I'd post it here first to see if anyone else has heard of this. Any ideas besides get a better quality drive?
