Upgrading the hard drive in your MacBook is a relatively easy process. I’ll outline a couple different methods here for you.
Step 1: Connecting your new Hard Drive to your MacBook to prepare it for backing up.
Before you crack the case open you have to format and backup your existing hard drive to the new hard drive. I use an external usb case. Once you have the new drive plugged into your MacBook open Disk Utility to format the drive. Select Erase and the Volume Format should be Mac OS Extended (Journaled).
Step 2: Software needed to backup/clone your existing hard drive.
There are a couple of common options for software.
Option 1: Carbon Copy Cloner Free (donation accepted)
Select bootable clone. To do this, select your Source Disk “Macintosh HD”. Then select the Target Disk that we just attached and formated. Select Backup everything, and it wil indicate that the Target Disk will be bootable.
Once the options have been selected, click the Clone button to initiate the cloning process.
This will take about 1-2 hours.
Option 2: SuperDuper $28
Select source disk in the first drop down, the destination disk in the second drop down, and backup – All files in the final dropdown.
Click Copy Now and come back in an hour.
Step 3: (Optional) Verify the new Hard Drive is bootable
If everything went ok you should have a duplicate copy of you old hard drive. To make sure before you swap hard drives you can reboot your system and hold down option key. This will bring up the option to boot from USB. Select your USB drive and see if the system boots up ok.
Once it boots up ok, shut your MacBook down.
Step 4: Installing the new cloned Hard Drive in your MacBook
All that’s lefts is to remove the old hard drive from your MacBook and install the new one. Now when you boot your MacBook up you have a new drive (hopefully with much more space) running exactly as the old.
