But fear not – with the right guidance, it’s actually a pretty straightforward process. In this article, we’ll take you through the steps to format your external hard drive on a Mac, and give you some tips along the way.
Steps
Step 1: Backup Your Data
The first thing you need to do before you format your external hard drive is to make sure you have a backup of all the data on it. Formatting your drive will erase all the information saved on it, so it’s essential to keep a backup copy if you want to keep your data safe.
Step 2: Connect Your External Hard Drive to Your Mac
Connect your external hard drive to your Mac using the appropriate cable, whether it’s USB-C, Thunderbolt, FireWire, or another connection type. Once it’s connected, you should see the external hard drive appear on your desktop.
Step 3: Open Disk Utility
To format your external hard drive, you’ll need to use Disk Utility, an application that comes pre-installed on all Macs. Open Disk Utility by clicking on the magnifying glass in the top-right corner of your screen and typing “Disk Utility.”
Step 4: Select Your External Hard Drive
Once you’re in Disk Utility, you should see a list of all the drives connected to your Mac. Select your external hard drive from the list on the left-hand side of the screen.
Step 5: Choose Your Format
In order to format your external hard drive, you’ll need to choose a format type. If you’re only going to use your external hard drive with Macs, the best format to choose is Mac OS Extended (Journaled). But if you’re planning on using your external hard drive with both Macs and PCs, choose exFAT.
Step 6: Name Your External Hard Drive
Give your external hard drive a descriptive name that you’ll be able to recognize easily. You can call it whatever you want – just make sure it’s something that makes sense to you.
Step 7: Erase Your External Hard Drive
Now it’s time to erase your external hard drive. Click on the “Erase” button in the toolbar at the top of the screen, and then click “Erase” again in the pop-up window that appears. This will delete all the data on your external hard drive, so make sure you’ve backed up everything you need before you do it.
Step 8: Confirm the Erasure
Before the process begins, you’ll be asked to confirm that you want to erase your external hard drive. Double-check that you’ve backed up all your data, and then click “Erase” again to confirm.
Step 9: Wait for Your External Hard Drive to be Formatted
The formatting process may take some time depending on the size of your external hard drive, so be patient and wait until it’s finished. You’ll be able to see the progress in the bottom of the Disk Utility window.
Step 10: Eject Your External Hard Drive
Once your external hard drive has been formatted, it’s important to eject it properly before disconnecting it from your Mac. To do this, right-click on the external hard drive in the Finder window and select “Eject.”
Step 11: Disconnect Your External Hard Drive
Once your external hard drive has been ejected, you can safely disconnect it from your Mac. Unplug the cable and put your external hard drive away until you need to use it again.
Step 12: Repeat as Necessary
If you have more than one external hard drive that needs to be formatted, repeat the steps above for each one.
