I was recently contacted by a person attempting to copy their Yamaha Electone Performance Disks. These files are not visible on Windows, and if you attempt to open the drive you’ll see “The disk in Drive A is not formatted.”
However, I was able to open them with WinImage (https://www.winimage.com/).
This will allow you to write them to another floppy disk, or store the files for the future.
The software is shareware, and costs $30 after 30 days; however, this will give you plenty of time to verify that it works for your disk duplication needs!
You can also save these images as .ima files, and they should be suitable to convert to .hfe files for use on USB floppy disk emulators such as the Gotek or Nalbantov. This is something to test.
You could also duplicate these disks using Keirf’s Greaseweazle, if purchasing extra hardware to do this is an option.
These files do not easily convert from Yamaha’s ESEQ format to MIDI.
