Disklavier

Good evening, everyone.

Mark, I am wondering if you have a mixture of double-density (DD) floppies and high-density (HD) floppies, all of which are formatted as DD disks. If so, that would explain why they used to work in the DKC500 xrg but may not work in a newer device.

Many of the older Disklavier control units did not know the difference between DD and HD disks. Although I am not certain, this may be the case with your DKC500 xrg. If so, disks that were formatted in the old control unit would have been formatted as DD disks even if they were HD disks. Newer drives and operating systems, however, know the difference between a DD and an HD disk (because the HD disk has a permanent hole on one side). The newer devices look at HD disks and expect HD formatting and are stumped when the disk was formatted as DD.

If this scenario fits your situation, use a piece of tape to cover over the permanent hole in the HD disks and try reading them again.

Regards,
PianoBench
