Here’s how to find out if your hard drive is faulty with Disk Utility

If you believe that the hard drive in your Mac or external storage system is a disadvantage, you may be able to use the first aid feature in Disk Utility to check.

The first aid feature in Disk Utility does a series of checks. If it detects a disadvantage along with your hard drive, it will be repaired.

Note: The Disk Utility has been slightly redesigned in OS X El Capitan. As a result, the best way to improve a hard drive has changed significantly. The steps to be performed depend on the MacOS model used. We are assuming that you have been using a model that is newer than El Capitan since this model was introduced by Mac OS X in September 2015.

To run First Aid on your Mac to find a disadvantage with your drive:

  1. Open the disk utility.
  2. Select your system with which you have points in the sidebar.
  3. Click First Aid.
  4. Disk Utility checks the partition game cards on the disk and lots. If you only provide first aid for a lot, Disk Utility will only check the contents of that lot.

If the hard drive is found to be at a disadvantage, the hard disk utility will attempt to repair it.

If Disk Utility tells you that the disk or volume will fail, restart and change it. Disk Utility cannot fix it.

If the disk utility detects that the disk is OK, it means that the disk has no disadvantage.

Repair a hard drive with Disk Utility

How you recover a hard drive depends on whether it is your Mac’s startup disk (the disk your Mac is running on, the location of your work system), or a person’s disk connected to your Mac. If it is your startup disk, continue with the next section.

  1. Open Disk Utility (Applications> Utilities or Disk Utility in the cmd + section).
  2. Select the amount for which you need to provide first aid. This can be an external tedious drive (if it’s your personal Mac drive, you’ll need to skip to the next part).
  3. Click First Aid.
  4. Click on Run. This starts the review and recovery course from.
  5. When Disk Utility is running, checks are performed and you see a drop-down record with the status. You can click the triangle on the back for more information.
  6. If no errors are found, you’ll see an inexperienced check mark at the top of the drop-down list.
  7. If errors occur, Disk Utility tries to repair them. (In older versions you had to select Repair Disk manually).

If Disk Utility cannot restore the disk or think the disk is faulty, you may be warned. If so, update your files earlier than it’s too late. Read this article on backing up your Mac.

How to restore your boot disk / boot disk using Disk Utility

You can run first aid on your startup disk as described above. However, if the disk utility detects errors, no attempt is made to repair them.

If you want to restore your Mac’s startup disk (the startup amount), you may not be able to do so because Disk Utility cannot restore the amount provided (the amount each part is working on). In older versions of the hard disk utility, the selection “Repair hard disk” is grayed out.

In this case, you want to start your Mac in recovery mode and restore the hard drive from the hard drive. This means there will be issues with the amount of Recovery HD created when pasting macOS. (Note that problems with a Fusion drive are even more complicated.)

  2. When your Mac boots up, a utility screen will appear. Choose Disk Utility.
  3. Select the hard drive you want to improve from the menu and click First Aid. As above, Disk Utility does its checks and checks if it can be repaired if it can.
  4. The recovery course from could take a while.
