I don't *think* this is a format issue (has that binary even changed in years?). The CoCoSDC firmware expands when you write, and format (if you just do LOGICAL) only writes LSN0, the allocation tables and the root directory. If you try to do a physical, that fails since it is not needed/supported by the SDC device driver. Similar things happened with other types of hard drives that didn't need low level formatting (the driver did not use it).

I was then able to use the mb.floppy script to create a new boot disk with all of the drivers I wanted (it fails on the format, but the image is pre-formate so that doesn’t really matter) on the 40DSDD image.   Setting drive0 to the new boot disk and drive1 to the 128MB image, I have what I need.

That's cool - I didn't know there was a utility for that, but I suppose something had to be making all the .dsk images. I'll check in to that too.

Darren sent me some BASIC code that will do this on the CoCo. I will be giving it a shot tonight.
