MAC Cloning Guide
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 using Apple’s Disk Utility (included with OSX, located in Applications > Utilities folder)

1. Once you have opened “Disk Utility”, click on your new drive on the left-hand side and then click on the “Partition” tab on the right. Once you are on the “Partition” click “Options” at the bottom. The next step is to choose the partition map you want to use.2. If you are formatting this drive for use as a drive on a PPC based Mac select “Apple Partition Map” and click Ok. This is the default partition map for all external drives. Intel based machines can read and write to a drive with a “Apple Partition Map”, however you cannot boot of off this Partition map on an Intel Mac.
3. If you are formatting this drive for use as a drive on a PPC based Mac select “Apple Partition Map” and click Ok. This is the default partition map for all external drives. Intel based machines can read and write to a drive with a “Apple Partition Map”, however you cannot boot of off this Partition map on an Intel Mac.
4. Select GUID partition for Intel Based Macs. This will allow you to boot your Intel based Mac off of this hard drive. Click “OK”.
5. Enter the name you want for the hard drive and click “Partition”.
6. You will be prompted with a warning message “Partitioning a disk will destroy all information on the volume of the disk.” To continue with the format, click “Partition”.

You will see a progress bar, once it is finished you will see your new drive on your desktop. You have completed formatting your drive for PPC or Intel based Partition Map.


There are many cloning programs out there. All are similar in cloning ability, but others may offer additional functions you may find useful. Some of the more popular ones are…

Apple’s Disk Utility (included with OSX, located in Applications > Utilities folder)

Apple’s Disk Utility (10.3.x or Later)
Disk Utility does have the ability to clone your hard drives just as well as any other software out there. All you will need to do is…
1. Select your new volume (indented) and click on the “Restore” tab.
2. Drag your old volume to the Source field.
3. Drag your new hard drive to the Destination field.
4. Click the check box for “Erasing Destination”.
5. Click restore at the bottom and it then will start copying over to your new hard drive.
Verifying your clone is Bootable To do this, restart the computer and hold the “Option” key on your keyboard to load up the boot menu. You should see your old hard drive and your new hard drive as bootable drives. If you do not see the new hard drive, you will need to do the cloning process again. If you do see the new hard drive, click on it. Your Mac will boot into it and you will get your desktop. This will verify that your hard drive has cloned successfully. Before reformatting/erasing your old hard drive, you will want to verify the cloning processes was a successful, as well as being certain your new clone works exactly like your old hard drive. Be sure to include checking your applications, data files, etc. Please see YouTube videos for assistance:https://www.youtube.com/watch?v=lfJrAcnHN2ghttps://www.youtube.com/watch?v=VqUJdQlgumY

4. Swop the HDD and SSD
View the following video before you continue: https://www.youtube.com/watch?v=7B2HOORy0hA
Should your laptop’s covers look different from the video please do the following:

  • Open an internet browser
  • Open Google.com
  • Google: Video of hard disk replacement on {enter your laptop make and model here}
  • I.e. if you have a MSI GS75 you would google “Video of hard disk replacement on MSI GS75”

Please make notes from the video, alternatively view it on a separate device.


Make sure your laptop is shut down and unplugged. You now need to unplug the external drive bay and remove the SSD from the external hard drive bay.


Next you need to remove the HDD from the laptop and replace it with the SSD, as per the video instructions.


Once the SSD is installed in your laptop, you can boot up normally.
All that remains now is to install your old HDD in the external drive enclosure:
Follow step 1 to step 3 under: “2. Installation of SSD into drive enclosure SSD”, this time fastening the screws to ensure that the drive will not slip out.


You can now plug the external drive enclosure into your laptop, and it will be accessible for either extra storage space or to use as external backup.

Congratulations, you have completed the cloning and disk swop out process!
