OK....let me reiterate....the discs are read just fine by the controller on the Disklavier and it will play wonderfully reading from the discs....when I remove the disc from the controller and plug it into my external Yamaha (a) disc drive THEN I get the popup that the disc needs to be formatted....ergo, the discs have not gone bad....so I wrote to Yamaha.....btw Yamaha will answer via phone call and email within 24 hrs.....anyway I explained what was happening and he thought for a while and replied "hhmmmmm, that's weird".....he did tell me how to get the MIDI files from the controller into Cubase so.....once I do that I'm starting over with brand new discs I can save them....The reason I'm makingsuch a fuss over this is because one of the discs is suppossed to be a digital copy taken from a reproducing piano roll of Gershwin playing Gershwin
OK, thanks for clarifying.
If you were shown a way to get the midi into cubase then you're saved.
Do this ^ and save as .mid then call that you're backup. Backup the backup because why not.
This page has a tool which should allow you to convert midi to the appropriate format for the disklavier. Do that.
Now take a new blank floppy disc, format it as (i guess) fat32, copy the disklavier "midi" file to it and try it in the piano.
If all of the above works and the disc is readable why both piano and computer, then you've got yourself a workaround.
