Update from some more reading....
Seems like Norton Ghost is the best way to go here, unless someone else has
any other ideas.

Am I correct here in assuming that one CAN (simply) replace their original

Do the drives have to be the same size for Ghost imaging? Hopefully
not!!!

The more I think about this, I think it would have to be done with Ghost,
or
something like that, to prevent reinstalling everything all over again.
I
doubt if the HD manufacturer's utilities would be enough.
