The "new" disk needs to be exactly the same size, or larger. Note
that some manufacturers sell drives that are 80 million kilobytes
as 80 Gb, while other manufacturers sell a drive that is only
80 billion bytes as 80 Gb. So even if they are both "80 gig" they
might not be the same size.
When you've copied it, and the second disk is larger, you have a
couple of options. Leave the unused space at the end as it is, or
try to use it.
You could just add an extra partition at the end provided you already
had an extended partition. That's the easiest. Expanding the
partition closest to teh end is the other option which risks losing
the data on that one when not done exactly right...
