Before You Begin

Before you start formatting your Seagate hard drive, make sure to backup any important data stored on it. Formatting will erase all the data on the drive, so it’s essential to create a backup to avoid losing any valuable files.

Step 1: Connect Your Seagate Hard Drive

The first step is to connect your Seagate hard drive to your Mac using an appropriate USB cable. Ensure that the connection is secure, and the drive is powered on.

Step 2: Open Disk Utility

Next, open Disk Utility, which is a built-in utility on macOS that allows you to manage storage devices and format them. To open Disk Utility:

  1. Click on the Finder icon in your dock.
  2. In the menu bar at the top of your screen, click on “Go”.
  3. A dropdown menu will appear. Select “Utilities”.

In Disk Utility, you will see a list of all connected storage devices. Locate and select your Seagate hard drive from the sidebar on the left-hand side of the Disk Utility window. The drive will be displayed with its name and capacity.

Now that you have selected your Seagate hard drive, it’s time to erase and format it:

  1. In the toolbar at the top of the Disk Utility window, click on the “Erase” button.
  2. A new window will appear. Here, you can choose the format for your hard drive. For compatibility with Mac systems, we recommend selecting “Mac OS Extended (Journaled)”.

  4. Click on the “Erase” button to start the formatting process.

Step 5: Wait for Formatting to Complete

The formatting process may take some time, depending on the size of your Seagate hard drive. During this time, it’s essential not to disconnect or interrupt the process to avoid any potential data loss or damage to the drive.

Step 6: Verify and Eject Your Seagate Hard Drive

Once the formatting process is complete, you should verify that your Seagate hard drive was successfully formatted:

  1. In Disk Utility, locate and select your newly formatted hard drive from the sidebar.
  2. Click on the “First Aid” button in the toolbar at the top of Disk Utility.
  3. Disk Utility will check and repair any errors on the drive if necessary.
  4. Finally, click on the “Eject” button to safely remove your Seagate hard drive from your Mac.
