I accidentally pressed record on my MZ-NF810CK without pressing the end search button and I think I recorded over the beginning tracks of my minidisc and now I've got a disc that only reads error when I try to play back. There are 38 tracks, songwriting ideas (ahhh!), that I can't access. Is there a way to uncorrupt my disc? I've uploaded the sonic stage software in hopes of being able to upload the informaiton onto my computer, but info doesn't go from MD to computer. Please give me some tips or pointers, thanks.
