Hi folks, I need some advice from all you techies out there! I have a MacBook Pro 15" 1.83GHz Core Duo with an 80Gb hard drive which is now full. I have bought a 320Gb replacement hard drive, and was going to swap this weekend using the brilliant guides on iFixit. I have an external USB 2 drive on which I have cloned my internal drive using Personal Backup 4, and I have confirmed several times that I can boot from this. My question is this... after the physical swap, what do I need to do to prepare the new drive for use? Is it as simple as just cloning directly from the external drive? Or do I have to format, initialise the new drive, or do something else? Many thanks in advance! Effortless.
