Disklavier

Hi Midi Magic-thanks for replying concerning my disk problems.

1.The files were not downloaded from Yamaha. They came from various sites 
plus some came from some software on my computor-such as ther Jazz Pianist.  None 
will play anymore except the PianoSoft disks I got with my piano.

2. I tried to copy them on the GranTouch but it still says unformatted disk.

3. It has not been near a large magnet as far as I know.

4. I went to some of the places where I had downloaded them and tried to do 
it again and sometimes the disks I used {Sony,etc.] worked and sometimes they 
didn't. The blank disks I bought from Yamaha work perfectly.
