Michael,

I'm not sure if this is your problem but there are some 3.5" drives that
don't work well with Disk2FDI.

List of Disk2FDI-compatible hardware
------------------------------------


Known 3.5" floppy disk drives with a real index signal (good):
- Hewlett Packard
        - D2035-60121
- Mitsumi
        - MF355F-3250MG
- Samsung
        - SFD-321B
- Sony
        - MPF920-E
- Panasonic (Matsushita)
        - JU-257A606P

Known 3.5" floppy disk drives with a fake index signal (bad):
- Alps Electric co., ltd.
- Mitsumi
        - D359M3
        - D359M3D
        - D359T6
- Nec
        - FD1231H

-----------------------------------

I've been using the Nec - FD1231H (fake index signal) and using a cable to
get the index signal from a high-speed parallel port and it works
flawlessly but when I try to use it without the cable (two drive mode) I
get results similar to what you describe.
When using the Sony drive (real index signal) I have no trouble with
Disk2FDI reading 5.25" Apple II disks in the "two drive mode".
