The FD-2000 can format the older 1581 capacity plus the High Density. CMD used the TEAC PC mechanism, but they had to tweak the circuitry in the small PCB on the mechanism to work properly. I figured out the Disk change and 2 other small components I had to swap around a little. BTW I have my original FD-2000 that has been tweaked, looking and comparing my tweaked TEAC to my NEW untouched TEAC I found 1 small resistor and a jumper. Ray Carlsen in the US (hes an older guy that has repaired Commodores for a lot of years) Ray told me about the Disk change, You install the standard type of Resistor on the DATA pin and then on the bottom a smaller resistor you solder the larger standard resistor to that, in doing that the Disk change does work.<br />As for Formatting a disk, copying data, etc the disk at times seems that it doesnt format correctly, etc. If you have any ideas on where I could make the needed hacks to this I would be greatful. If you need more info just let me know I can send you pictures of this issue.

And the same works for mobo vendors, chip vendors, etc.<br />Did you saw the mark FDD near the 34-pin connector on your MB? Even when the "FDC" chip, or the actual part of the onbaord chipset doesn't support the older 5,25" floppies, it is still called FDC! Likewise, the connector assigned to that drive is still called the FDD connector, even though, the connection doesn't support the 5,25" floppy drive.<br />Think about it. ;-)<br /><br />Paul: Great article!
