First off, thanks for taking the time to help me A440. When I put in a recorded disc into MD and connect via USB I do see songs Under the MD unit. However, I am not able to transfer music to a blank without getting the previous error message. I hadn't tried MDAC repair tool until now. I've downloaded it and I selected the "Pre-register the MDAC" button on both MDAC, and JET tabs. It did not fix the problem. Is there more to the MDAC repair tool than that? Chris
