ubuntu : copy to new hdd?

[betty]

ok, i *really like *ubuntu (feisty fawn) . i have it set up 'just like i 
like it' to be. (on the gui)
i will start to use that and phase out rh 9.0 that i've been using forever.
the ubuntu is great, it worked easily on my palm :)
on my printer:) and on
the ext modem :)
what more could one want !

BUT it is on a 10GB hdd :(
i have an 80 gb hdd that i can wipe out the current file system and use 
that.

what commands do i use to copy the 10 gb hdd set up (like a mirror?) to 
the 80 gb hdd??? then i'll just use the old 10 gb hdd for some other 
project.

probably a stupid question right?
thx.
