This will ALMOST work.  If there are any references on your external drive to
other folders by Directory ID (DirID) rather than by path name (the Apple
recommended approach), these references will become scrambled, since the
Finder will assign new Directory ID's when copying the files.  I got (mildly)
burned by this when I backed up my disk, formatted with Silver Lining, then
restored (so that I could mount the HFS volume on A/UX).  The two things
that I've found (so far) that reference folders by DirID are SuitCase II
and AppleLink.  I will probably be finding others over the next several
months.  (Note: I used DiskFit's Disk Duplicate function rather than a 
Finder Copy, but I suspect a Finder Copy would have the same problem.)

If you DO use a Finder Copy, make sure you have plenty of memory.  (Don't
do this under MultiFinder, or you may run out of memory halfway through.)
