Cloning Your Data to A New Hard Drive in Mac OSX by Jon Gunnison

There are plenty of ways to clone your older hard drive to your new hard drive. Laptop models - you may want to format and do the cloning process with the new hard drive inside of an enclosure before opening up your computer. If you purchased the Universal Drive Adapter, you already have the tools required for your laptop model computer. Tower models - you can install the hard drive inside of the computer without taking out the older one you will not require an enclosure. Note: Older Macs using ATA type drives may require you to configure the new drive as "slave" using the drive's jumper(s).
Booting into Your Old Hard Drive
After you install the new hard drive, you will need to boot to your old hard drive. If you have an external enclosure for the old hard drive, you will plug that in via Firewire or USB, (Note: USB is only a bootable option on Intel Macs) then turn on your computer while holding down the Option key on your keyboard. This will give you a boot menu that looks like the picture to the left. Click on your old hard drive to start the booting process, and your Mac will start up normally after that.
Formatting Your New Hard Drive
Formatting the new hard drive will be the next step you will need to take to add a volume to the drive. Here is an instruction guide for the formatting process. http://www.newertech.com/tech_support/manuals/HDDppcintelformat/HDDppcintelformat.php
