Hard Disk repair and File System fix for Mac

So you don’t make any mistakes we recommend getting one of our Mac hard disk repair experts in to assist you. We can fix Mac OS X File System errors on MacBook Pro and Air laptops and iMac desktop computers.

Basic ‘First Aid’ using the Disk Utility for hard disk repair

  1. Use Spotlight Search in the top right of your screen then search for ‘Disk Utility‘ and open it
    1. Alternatively you can reach Disk Utility by opening Finder > Applications > Disk Utility
  2. Select the disk or partition on which you wish to perform ‘First Aid’ or ‘Verify Disk’
  3. Use the Verify Disk to check for errors
  4. Use Repair Disk to repair problems with your disk or partition

Clicking ‘Show Details’ will give you a run down on the findings. If you see messages such as ‘exit code 0’ the ‘0’ is a good thing!




Booting in ‘Safe Mode’ to repair your Mac or Disk

  1. Reboot your iMac or MacBook and hold shift while booting to enter Safe Mode/Safe Boot
  2. Sign-in with your administrator login details

The automatic utility will now check your disks so this could take quite some time, please be patient.

Once you are logged into your Mac via Safe Mode please reboot again and you should be OK.

Using ‘First Aid’ in Recovery mode

This is your final option.

  1. Reboot your iMac or MacBook and hold Command + R while booting to enter Recovery Mode
  2. Choose the ‘Disk Utility‘ icon to launch the utility application
  3. Select the disk or partition on which you wish to perform ‘First Aid’ or ‘Verify Disk’
  4. Use the Verify Disk to check for errors
  5. Use Repair Disk to repair problems with your disk or partition

Once again if you view extra details and notice ‘0’ after the exit codes this is good!

Repairing your Mac in ‘Single-User Mode’ with fsck

If all the above options fail to complete your Mac hard disk repair you can use the ‘File System Check’ command via Terminal.

  1. Reboot your iMac or MacBook and hold Command + S while booting to enter Single-User mode
    1. You should now see a black text-based terminal
  2. Type the following command to start the file system check process: /sbin/fsck -fy
    1. Once the process has completed successfully you will see the message
      ‘** The volume [system-name] appears to be OK’
    2. If errors were found during the process you will see
      ‘***** FILE SYSTEM WAS MODIFIED *****’
      the fsck command should have fixed the disk problems at this point
    3. Sometimes is a good idea to run this fsck command a few times to repair additional errors until non are found
  3. Now that we are done repairing the system you can run the reboot command to restart the computer
