Here is somethin for your TDK. The link will have your drive up at the top of the page. I'd recommend the
RPC1 and Rip Lock firmware based on Windows 1.33.

As for your Lite-On, Ill need more info. Like what model it is. I dont need to know how fast it is. Just the model number like you gave me with your TDK. If you dont know just open up a burning program and see what it calls your drive.
Tyler!
