"device copy"

[camner]

I was perusing the ProSoft website and reading about Drive Genius (I'm considering it as a way to repartition "on the fly") and they claim to use a "device copy" method that differs from "file by file" copying.

I'm curious...does SD! do "device copying" (which I think I understand is a bit by bit copy") or "file by file" copying...and what are the advantages, if any, of one method over the other?

No. We copy file-by-file, which allows us to do Smart Update and other kinds of intellegent selection and exclusion, we won't copy directory corruption, etc.
