If this device works successfully with the Casio FZ-1 and FZ10M sampler, you'll have plenty of people wanting them. The FZ-1 drives die a lot. Mine is still going but I nurse it and I know one day it will go. I'd love one of those - and not just for the future security of my FZ, but because I could have my whole library on 1 stick!
If you want some more specifications about the FZ-1 floppy drive, you can find them here:http://www.buchty.net/casio/fz1-diskdrive.html
Would that help you evaluate whether its possible? You may have already seen that site, but just in case you haven't.
This is really great news! So, how much is one of these drives likely to cost?
