I've decided I am going to replace my existing 120Gig drive in my MacBook Pro 15" 2.33 Intel with a new Western Digital 320Gig. I use the thing so intensely, I never have any free space. I've got the drive but want to ensure as perfect a clone as possible. How should I go about this. I do have another identical (spare) MacBook which has a dodgy logic board but works fine, so I was thinking of putting the drive in that and doing a firewire clone??? then swapping them over. My main question is would I need to install Leaopard on the new drive before I attempted the clone. Maybe I should use disc utility. I dunno... Suggestions?
