Floppy drive programming --- experts, please come in - China DOS Union Forum

There is a kind of floppy disk that can be used in the early IBM 640K floppy drive (note: it's a 3.5-inch disk, and it only existed for a few months before being eliminated by 720K). I do embroidery design work, and we usually have to use an embroidery design software program to read the files on this kind of floppy disk. If WINDOWS is used to read it, it will be treated as bad sectors and prompt for formatting.

I took the floppy drive casing apart, used the embroidery design software to open this kind of floppy disk, and then opened this floppy disk in WINDOWS, and found the following problems

1。WINDOWS reads directly starting from track 0
2。The embroidery design software moves directly from track 0 to about track 30 and starts reading

I asked a few friends, and they said they could use the INT 13 instruction in assembly to interrupt the floppy drive, then move to the specified track and start reading. I don't know whether anyone here has run into this kind of problem before. If convenient, please provide related technical information, digitizing@mucun.com

Well, this requires very advanced hardware knowledge.

Why not copy this disk to a 1.44 drive? It can be done with the software "800II".
