I'm having some problems with my NH-1. I has hoping someboby on this forum could help me. I was using it to record my piano practice sessions. I was recording in small bits (about 20 sec.), and after some time (when I had about 120 tracks the first time it happened, and almost 300, the second one), I got a "Disc Full" message, and the last tracks had no music on them, just strange noise. When I tried to download the tracks to my PC (some tracks still were good) , they wouldn't. The folder to which I tried to download them was empty. When I removed the disc and inserted it again, I got a "Format Error" message. What could it be? I was thinking that maybe it was because I put the minidisc on the piano, and the vibrations had something to do with it. Should I get it repaired or something? Has anyone experienced something like this? Thanks.
