Thanks for the offer of help in this matter. I believe my client cannot access any of the information on the memory disks. He claimed to have a large number of recordings ( about 75) on memory disk number 1.
Then his daughter was recording herself playing and accidentally shut the unit off before it was finished writing to the disk. I was not there so I do not know exactly how events happened. My client would like to recover this data, if possible. Thank you all so much for being willing to share information.
