First, thanks for your tips!  I am sincere here and please do not be offended 
if I come across as an ignorant idiot, of which I can be at times.

What happens when you have a multiboot drive, of which there are windoes of 
many variants (98,2K,XP,...), Solaris, Linux(Fedora,Ubuntu,...)?

Which is why it is not so simple. :-/

Also - manually "walking through" each partition of the source drive and 
manually creating/copying partitions to the target drive could be quite a 
chore I think, and getting all of the MBRs for each partition could be a 

Which is why I said: "semi-clone" tool...

I must be joking, right?  Unfortunately, no.  Am I asking for a "pie in the 
sky"?  Maybe.

But then that is why I am asking - although you are absolutely right, I did 
not 'specify' the conditions and I apologize for that - must be getting old 
at my age and forget important details.  *sigh*
