I'm having the same problem, with my MZ-N1. I acts as if the song has transfered fine, but when I go to play it back nothing is there. Infact it tells me blank disc, I tried 3 different brands of MDs, I've downloaded the latest sonicstage 3.2 I have sonic stage 3.1 and everything was working finr until monday. All of my old discs still play fine. Anyone got a fix?
