i was using my sony mz n-10 net minidisc with sonic stage program it came with when sonic stage crashed. The disc that i was using at the time is now completely unusable- i can't even erase it. If it's any help it just says 'TOC error' on the screen. Is there any way that i could restore what was on it? -It was full of irreplaceable recordings from radio. If this is impossible i would just be really grateful if somebody could tell me how to erase it so it could be reused. thanx
