How do i repair an external hard drive on Mac?
1. Check your cable and ports
Faulty connections are often to blame for external hard drive issues. Before diving into any troubleshooting steps, make sure to plug the hard drive into another port. If the current port is the problem, your Mac should be able to recognize the external storage device and access the files stored on it after you plug in another port.
The USB cable might also be the culprit. Use another cable to connect your hard drive to your Mac and check if the problem is solved.
If the device is still unusable, go to the next step.
2. Use Disk Utility
Disk Utility is a very useful built-in troubleshooting tool that you can use to detect and repair many hard disk issues.
Here’s how to use the Disk Utility to repair your external hard drive:
- Navigate to Utilities > select Disk Utility
- Click on View > select Show All Devices to list all the devices connected to your Mac
- Select your external hard drive
- Go to the sidebar and click on the First Aid button
- Click on Run to launch the tool. Disk Utility will now scan your external hard drive and repair the issues detected.
Wait until Disk Utility confirms the drive has been repaired. For additional information, you can click on the Show Details button to learn what has been repaired.
If Disk Utility reports it could not repair your hard drive, repeat the same steps again. If you get the same message, you need to format your external hard drive.
