Greetings to the group from Connecticut. My name is Herb Lindahl and I have been in the Piano Tuning and Restoration business for 30 years. I have a client here in CT with a Disklavier with the DKC55rcd Control unit. He has owned it about ten years. He has made many recordings of himself playing over the years. Recently, his young daughter was recording herself playing, and while the song was saving to a memory disk, she, by accident shut the unit off. Now my client cannot access any of the music he had stored on the unit. Is there a way to restore his music, or could it all be lost ?
