the best way to copy all files from one hard drive to another is to use a disk cloning application such as [http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html|SuperDuper!] or [http://www.bombich.com/|Carbon Copy Cloner]. Both programs are free and work very well if you're copying your whole drive and not just your user documents, these programs will ensure that everything is copied including hidden files and important system files. if your intent is to make an exact duplicate bootable drive, then copying files using the Finder will NOT work - the disk will not be an exact bootable copy.
