this problem also happens to me. I'm using a Sony N-10 and Sonic Stage 3.1 whenever i try to transfer a track onto the md always the error msg comes up: "Unable to transfer the track or tracks." does anyone know why this happens? I've tried the different recording modes from SP,LP2,LP4 and none of it works still comes up with the same error message. From the specified transfer mode selection and also the other 2 transfering methods, SP transfer mode and standard transfer mode. The music i'm trying to transfer are .mp3 file format All the bitrates are: 192 and sameple audio rate at 44hz.
