[Coco] CocoDisk was: nitros-9

[Bob Devries]

Thanks, Darren. I tried a different disk, and was rewarded with success.

Also, when reading a disk and creating an image, even a partial file is 
better than no file. In some cases, the files can be retrieved from the 
image and transferred to another image disk.
