I have a follow up question on the same topic. I just bought a Sony MZ-RH10 (its my third Sony MD player since 99). I recently recorded a concert in Hi-MD mode and it came out great. When I went to transfer it to my PC via SonicStage, something went screwy and the disc won't play. I don't understand how this happened because right after i tried (unsucessfully) to transfer the recent audio i recorded I popped an older minidisc (with a previously recorded concert into the MZ-RH10 and tried to transfer that audio. That didn't work either so I put the new MD with the new recording back into the MZ-RH10 and got the "format error disc" message. The older minidisc with the older concert was fine -- no damage. The new one wont play at all. The unit keeps asking me to erase what on it so i can reformat the disc. I have read a few threads that say I'm basically out of luck. Sony told me the same thing. However, I was wondering if anyone knows of any services that specialize in recovery of audio files such as these. This is a recording of a one-time event, and I would like to retrieve it if possible. It seems rather rediculous that I would lose the entire show for basically no good reason and Sony is insisting the unit us functioning properly. None of my previous MD recorders worked this way. If anyone has any thoughts, please drop me a line at frankiekp@yahoo.com thanks --Chris--
