Cloning from a larger hard drive to a smaller one is possable IF the
Source drive has less bits o nit than the Target drive can hold. I am
doubting that. But TRUE cloning, Again making a Bit for Bit Usable Hard
Drive, does not use compression in the process.

Ghost had in the days I used it had TWO Functions just like TI. "Colne",
Making a bit for bit usable duplicate Hard Drive. Or Making a "Image",
with compression if selected, for a backup of the hard drive that needed
to be Restored to the Hard Drive for use.
