Right. Let me ask you this, Anna: does it end up doing exactly the same
thing, or does it just do a quick scan and leave it at that (and not go
through all the dvice recognition and setup stuff it does when it reboots)?
I'm guessing it does exactly the same thing, though, but at least saves the
reboot time - but only that. IOW, there will still be a device
recognition time of a few minutes where it sets up all the drive letters and
all that. More below.

OK, I'm going to look into this a bit more, and try to "get to the bottom of
it" (as to why it can do that, but ATI can't, or whatever). Evidently
Casper must then rewrite the clone HD signature to the clone drive's MBR
*right after making it* (and it has to be rewritten, because it still
contains the identical cloned MBR values from the source drive, and that
signature must be unique for each HD). At least as I understand it.
Not having to open up the case and disconnect the main drive, and then
having to boot up one time on the clone to make sure its properly
initialized, and then having to shut down and disconnectting the clone and
reconnecting the main drive once again (AND resetting the BIOS boot device
priority along the way) would be a nice thing.
