Disklavier

Unless Yamaha has any recovery tools or a utility to extract a raw dump 
of the memory disk storage, I think the only way to proceed would be to 
send the Disklavier control unit to a data recovery specialist or 
company like Kroll Ontrack.  That individual or company would need to 
desolder the flash chip(s) holding the memory disks, dump them using an 
external reader/programmer, repair the file structure (if anything can 
be salvaged at all), extract the files, then reinstall or replace the 
flash.  This will be very expensive.

The job can be divided into two tasks.  The first task would be to 
obtain the dump of the flash memory and reassemble the controller; the 
second task would be to study the dump and piece together any recordings 
that are still intact.  As the latter task requires some knowledge of 
Disklavier file formats, I would be willing to take a shot at recovering 
performances from a raw dump of the flash memory, if your customer can 
obtain that.  It would be less expensive than paying a data recovery 
service to come up to speed on these.

I have not seen the inside of a DKC55RCD.  If the flash memory is 
socketed or otherwise removeable, that would make the job of obtaining 
the dump much easier.
