OK. Leopard newbie here. The situation: MacPro - with 4 HD bays My boot drive is the stock drive in bay #1 I wish to start using the much faster drive in bay #2 as the boot/Applications Drive. In order to do that, must I... A- use Time Machine to migrate the entire contents of Drive #1 and move it to Drive #2?? B- I can't simply duplicate the contents and paste them into Drive #2. C- Must I start from scratch and reinstall the OS and simply target the drive in Bay #2?? I want to do this properly and without reinstalling everything from scratch.
