Thanks for all the advice. I am having some USB problems and considering starting from scratch with a fresh install of Leopard, iWorks08, iLife08, Final Cut Express, and Photoshop Elements. I would install fresh on a new 1 TB drive and remove the original 320. Do you know of any reason to be concerned that Apple or Adobe would prevent me from installing these aps in a replacement hard drive on the original computer? I can't imagine it would be a problem. However, a Best Buy computer employee opined apple and Adobe would deny me the ability to install the OS and aps on a different HD even if it is a replacement in the same machine.
