[Coco] Drive issue

[Daniel Campos]

ADOS are of no avail to me. I need a solution that works on the SDC-DOS, 
because I need to dump them into the CoCoSDC.
I think I will need to use my bulky CP-450 to read them. My MPI doesn't 
liked much the CP-450 last time when I plugged the two together. But 
that is another problem...
