I did something similar a few days ago, only upgrading from 6GB drive.

Use tar, it makes things easier.

(cd /; tar -clf -) | (cd /newhdd; tar -xpvf -)
(cd /home; tar -clf -) | (cd /newhdd/home; tar -xpvf -)
[etc, repeat for any other partitions]

The "-l" option tells tar to only do stuff on one file system, and "-p"
tells it to preserve all permissions etc.

It depends on the HD.  It's never really bothered me, though, because
fdisk does it for you.
