Hello,
Recently I was able to acquire a Mitsubishi 355C 252M, and I thought I'd be neat to put it in a Win98 machine. The drive should be a IBM/AT compatible, and it does work. I can write on floppy perfectly.
However, it turns out this thing can't read ''normal floppy's'', nor can a floppy drive read floppies I wrote with the Mitsubishi one (so lets say, I put a file from the Mitsubishi drive on a floppy, but when I put that floppy into another drive (lets say Samsung SFD-321B, very standard stuff) it doesn't recognise it). However floppies I wrote with the Mitsubishi drive do get recognised by the drive itself.
Maybe the jumpers of the drive are wrong, I did see DS jumper on 0 instead of 1, so the drive might come from a non-IBM compatible machine.
I did find the datasheet, but I have no idea what jumpers to shorty for IBM compatible (or if I need do it at all) .

LD/HD > HD shorted
DC/SR > DC shorted
MM/MS > MM shorted
IU/IS > IS shorted
FG > shorted but unchangable anyway.
However, there are also 3 other jumper I have no idea what they are supposed to do. These do not show up in above manual and are labeled ''H0, SW and HI. HI is shorted as seen in the foto below:

These are not the HD/LD jumpers as those are located somewhere else (DS 0/1 are also located somewhere else).
So does anyone have an idea why this drive is so weird? Am I missing something, or do I need to set jumpers.
Regards and thanks for your time 😀
