A disk utility can also fix and diagnose problems with a disk and damaged volumes.

Part 2. How to Use Disk Utility?

Now that we know that a disk utility is vital in making sure that Mac is running smoothly, there are also a lot of potential problems that can arise and cause a stir. There are a lot of reasons where you can use disk utility on Mac.

Here are the most common scenarios where you can run a diagnosis on your disk utility:

1. Your external device does not work

2. Unexpected closing or quitting of applications

3. Your device won’t start up

4. Corrupted files

5. When you need to erase, format and partition a disk

6. Damaged disk

7. When you need to eject or mount/unmount a disk

8. When you need to disable/enable journaling

9. Problems with the startup disk

The disk utility has been changed as the new MacOS versions upgraded. Many features were removed and new features were added.

Part 3. How to Repair a disk using Disk Utility?

Just like we mentioned above, there are a lot of things your disk utility on Mac can do.

For example, if the disk has problems and it is no longer letting you do anything on your device, you can scan and diagnose to understand the issue.

If your Mac still powers on, the best way to determine the status of your system is to use iMyMac-Cleaner. This is a safe and effective program that runs diagnoses and lets you know what is wrong with your Mac.

When you see that a disk error appears after scanning the entire system, you can proceed with the repair.

Hard Drive Recovery

Now we will perform a hard drive recovery using disk utility. Since we will need to restart your Mac, you can print out this article or open it on your iPhone or any Smartphone.

Restart Mac by clicking on Apple menu then Restart.

Upon restarting press Command+ R and holding until Apple logo appears.

Click on Disk Utility and click Continue

Find the disk from the sidebar that needs to be repaired

Look for First Aid and click. From here, disk utility will inform you about the status of your startup disk. If you receive this message, there is nothing much we can do if the disk is on the edge of failing.

Simply backup the entire Mac and bring it to the nearest Apple store.

If Disk Utility gives you another option which is to run diagnostics, click Run.

After running diagnostics, Disk Utility will inform you that the disk has been repaired.

 

That’s it! Your disk is now repaired and you can continue working on your Mac

Notes: However, there are some issues that may arise during the or after the diagnostics. There can be physical damages, reformatting needs, and other underlying failures.
