It's not the exact same model as your driver and not the same problem, but at your discretion you could give it a shot. Please don't blame me if it hoses up your system.
Other than that, I don't know what else to tell you. If you're technically inclined or know someone who is, you could always spend $20 on Newegg and get a nice new burner shipped...
