Does this require either or both of the drives to be unmounted. I was 
just thinking if whilst the copy was occuring if the source drive was 
written to, would that possibly cause the dest. to be invalid (or I could 
just mount read only) especially if the write occured before and after 
the current copy location (if that makes sense).
