Tri-Formats floppy disk recognition problem.

Hello,

i did some tests from a tri-format floppy disk (PC/ST/Amiga) from a raw stream converted first to SCP then to E-ADF. I tested the result under WinUae and I have some results (the same with SCP or E-Adf ) which I don't understand.

PC part:

Under CrossDos <= 5.07: PC part recognized (only Amiga side, pic 1 ).
Under CrossDos >= 6.0: PC part unreadable
The floppy disk is unreadable under PCX or PC-Task. On the other hand, it is perfectly readable with Transformer (and the file executes correctly, pic 2 ).

ST part:

Medusa (100% software): ST part recognized.
Chamaeleon 1.0 (100% software): ST part recognized and usable ( pic 3 ).
Amtari 3.1: ST part not recognized.
EmuTos: ST part not recognized.

What happens so that this only works in certain cases ?

Thanks.
