Hi
I am doing some test's on a Gotek Floppy Drive (so I can use large T values...I need them)
(The hfe file I have created will handle 160)
Not sure I have have found a bug or run into some limitation? Any input would be helpful ;)
Using 114 is OK, see below,
but after that I get Bytes available for files vs Bytes actually free does not match
