Hello all I'm new to this forum I've encountered a very strange and very sad problem- My minidisc fell (it wasn't playing when it fell). within it was a Disc that contained many persoanl recording. Once it fell, the MD could not recognize it and claims it to be a blank disc. It is not! I tried several times reloading it, loading different discs (that worked fine). only this disc's information is gone! How could it have been erased just by falling? IS THERE A WAY TO SAVE THIS DISC'S INFORMATION? Please, I would greatly appriciate any help!!! The music on this cd is precious to me... Thanks , hope you'll know what to do... eyal
