Can't duplicate any disk

[Pitou]

I'm trying to duplicate Workbench 1.3.

I made a lot of tests and made some great progress.

I can read almost any disk and save them into a .scp image and it works fine in WinUAE.

Now if I write back the .scp image to a real disk, that's where I have some issues. The real disk doesn't boot in a real Amiga and if I read again the disk I just wrote, then the .scp image doesn't boot as well in WinUAE.

In summary, I have a problem with write related to the drive. The same diskette writen with a real Amiga boots fine.

Now I have 2 questions:

1- Is there a way to fix the write in a floppy drive?
2- Regarding the Flux data image, why sometime I see "gap" or "blank" in the blue line?

Thanks!

Pitou!
