    Help with copy protected 400k floppy disk (CAD software for 68k)

    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.

    Recapping : if it ain’t broke don’t fix it?

    Thanks for your advices. As I don’t know how to solder and it’s difficult to find people that are recapping as a service in Europe, I was hoping that I could send for recap only one of the board of each system that I have ( I have 7 classic and a Lisa 2).  Given all the messages above, I think...
