You didn't mention the jumpers. How did you set them?

I knew that question would be asked -
The original drive (sony cd-rw CRX215E5) is set to master and is connected to the one that says master and the dvd drive is set as slave and is connected to the one that says slave. The dc input plug that says P2 is connected to the cd drive and the one that says P3 is connected to the dvd drive, it also has another plug that says P8 which is not connected to anything. The dvd drive is the only one that works. I hope that I am on the right track with the answer.
