The problem here is that those floppies were written in variable speed mode and we tu to copy them in fixed speed mode. Theoretically it should work but practically it’s unreliable. Then if you add bad sectors intentionally created for copy protection it gets even worse.
yes, using a flux imager with an Apple disk drive would probably give better results.
@olePigeon thanks for your offer, unfortunately I’m in Europe and I’m also reluctant to send them by mail.
The software I want to preserve is Bridgeport EZ-Draft CAD for Macintosh which is quite rare. The Master floppy disk is required when you start the program and I have difficulties copying it or dumping it. I tried with my Supercard Pro (SCP), a Deluxe Option board (DOB) and Copy II Mac 7 but...

I’m afraid...
Thanks very much for this comprehensive answer and I'm reall thankful that you offer to gracefully dump the disks, Here are some comments about your message :
John already confirmed to me that it would not be possible without some hardware modification. Anyway I don't have the Lisa OS 1.0 disks...
I have a full Lisa office suite in French on Twiggy disks.
My first objective would be to dump those disks in order to upload the images on archive.org and bitsavers.org. There is of course the problem that I don't have a twiggy drive, but I could lend the disks to someone that has one and...
