Guess that's because you format the disk as FFS or OFS. Something the PC drive can't do.
No, it's not because of that.
You could try to format it in a CLI or shell and specify that you want to format it with the crossdossfilesystem. Maybe that works.
No way.
A) You cannot specify crossdosfilesystem for format.
B) "Add PC drive A:\" doesn't make the drive available thru trackdisk.device or mfm.device. It makes it available similar to hard disk, that is filesystem bridge only. You can't format such drive.
Basically you need to use Windows side to format the floppy still. Also I doubt this A:\-mount handles disk changes well.
