Thanks Geoff. All the .dsk images I created seem to be around 95Kb (should be 180k).

I'll take another look at my PC BIOS settings regarding boot up floppy seek to see if that's causing the problem.

Once the .dsk image was created I saved onto a 1.44Mb 3.5" floppy. I then put this in a USB floppy drive and from there onto my Windows 8 laptop running CP/M Box. Could this have caused problems? I didn't think moving the .dsk file around using such methods would affect the file as it had already been created. I may be wrong though.

It looks suspiciously half of the required size, so maybe removing the double step may help.


Can you make an image of a regular CP/M disk that we have a good image for? That way we could compare the data on the dsk and figure out if double-stepping is the root cause for the problem.


I think that definitely it is the double step, try removing it first.

That's it! The step needs to be 1 for a 180k drive. I've just made .dsk copies of CP/M, Time & Magik and a RAM Test program and all run perfectly in CP/M Box emulator. Many thanks for all the assistance; I have been wanting to create .dsk images from 3" disks for about 10 years so it's so great to have finally succeeded  :D
