If I'm not mistaken, and I only know this to be true for Zip drives, the
utilities provided by Iomega set a fixed translation (geometry) that all
Iomega software recognizes. The SCSI controller has its own idea as to how
the disk should be setup geometry wise. Thus even if you had it MS-DOS
formatted, you would be unable to read it unless it was formatted as a
hard drive under DOS. I'm sure that there is someone working on this
problem, or it is already fixed.
