[Coco] Re: [Color Computer] Re: using Tandy FD drives in a PC

[Peter Singfield]

There was a Coco software we used especially for this -- believe it was
called "Clone" -- or Clone Master???

Basically -- it does a complete bit image of one disk to another.

Like Norton Ghost does today.

Actually -- should not Norton Ghost work??

Some software protection depended on leaving specific tracks unformatted.

"Cloning" worked well for those.
