How do you know if your disk needs repair

Restart Mac Disk Utility Mode

If you can still turn your Mac on, check the startup disk with an app called CleanMyMac X. Open its Maintenance module and run 'Verify Startup Disk'. If you get the 'Disk needs repair' error, your disk needs immediate attention.

Don’t worry, it doesn’t necessarily mean you have to replace it right away, there’s still a chance to fix it.

We’ll go over how to perform hard disk repair on Mac using software solutions. That’s only possible if your disk can be saved by means of Mac’s native app, Disk Utility. If it fails, the only alternative is backing up your data and getting a new disk.

Hard drive recovery using Disk Utility

  1. Print this article or open it on any other device. You’ll lose access to it after you restart your Mac later.
  2. Click on the Apple menu (top left corner), choose Restart.
  3. When your Mac restarts, press Command + R and hold the keys until the Apple logo appears.
  4. Select Disk Utility and click Continue.
  5. In the sidebar, choose the disk you think needs repair.
  6. Note, that if you are using FileVault to encrypt your disk, you must mount the disk first. To do it, click Mount at the top of the Disk Utility window. Then, enter your Mac account password in the dialog that appears.

  7. Find First Aid and click on it.

At this point, there are two options.

Case 1. Disk Utility might tell you right away that your current startup disk is on the very edge of failing. This means you need to promptly back up all your files and take your beloved Mac to the repair shop. That’s about all you can do.

How to back up your Mac

If you’ve never used Time Machine, you’ll need to configure it first:

  1. Connect external storage (AirPort Time Capsule, USB flash drive, portable hard drive, or else).
  2. Go to System Preferences and click on Time Machine.
  3. Click the Select Backup Disk button in the center of the window.
  4. Choose the storage device you wish to back up your files to and click Use Disk.

That’s it! Your first backup will be started automatically in a couple of minutes. More detailed backup information is specified next to the Select Disk button. We recommend connecting your Mac to a power cable before starting the backup.

If your Time Machine is already configured, you probably know what to do:

  • Click on the Time Machine status menu at the top right corner of the screen
  • Choose Back Up Now

Can’t see Time Machine among status menus? Then, open System Preferences > Time Machine and select the “Show Time Machine in menu bar” checkbox.

Case 2. If Disk Utility offers you to run diagnostics, simply click Run.

If it reports that the disk has been repaired, you’re free to close it all and live a happy life from now on. But, unfortunately, there can be other troublesome issues.

For example, Disk Utility may inform you that the underlying task reported failure. In this case, you can try to repair the disk again. If that fails, use our guide above to back up your files and then completely reformat the disk. You’ll need to remove all the info from it, reinstall the operating system and restore the data afterward.

If you continue having issues with your disk and neither recovery option works, it may be physically damaged. Which means you should take it to your local Mac service, they will be happy to assist you at this point.

How to protect a disk from failure and keep Mac healthy

Restart Mac Disk Utility Mode

With the proper software tools, you can monitor your Mac’s well-being and keep it speedy and sound for years.

There are two essentials to a good-working Mac: a clean drive and a fast system. Both are covered by CleanMyMac X. It removes useless files from the drive, monitors your Mac’s performance, and keeps your macOS running smoothly.

That’s about it with DIY Mac hard disk recovery. Hope this article helps, stay tuned!

What is Mac Recovery Mode?

Apple recovery mode is available in an emergency when your macOS is running into serious difficulties. There are four main features of Mac’s Recovery Mode, whether that is the regular recovery or internet recovery:

  • Restore from Time Machine Backup: Use a previous version of your Mac stored on an external drive. You will have had to prepare this is in advance by connecting an external hard drive and using Time Machine to copy all of your data, including files, OS, and settings. If you have an external copy, you can use this to restore your data under the ‘Restore from Time Machine Backup’ in Recovery Mode, which will erase the current disk.
  • Reinstall macOS: This wipes your current OS and its data and replaces it with a clean version. If you have any files you need saving, make sure that they’ve been uploaded to the iCloud or some other storage, whether online or on a separate hard drive. Which version of macOS that is reinstalled may depend on whether you run the normal Recovery Mode or Internet Recovery Mode.
  • Get Help Online: Recovery Mode allows you to use Safari to troubleshoot issues you may be experiencing.
  • Disk Utility: If you suspect there’s something wrong with your drives, you can scan, verify, and repair them from the recovery screen, which might be a quicker and more convenient alternative than erasing and reinstalling your macOS.

Now, if you are considering a complete restart in Recovery or Internet Mode, it’s recommended that you give your Mac a thorough clean first. Otherwise, this is like cleaning the house, then dumping everything you’ve hoovered back onto the carpet. The muck has only been moved around. With a tool like CleanMyMac X, you can declutter everything you don’t need, then back up safely (always best doing before restarting or rebooting), which means it should run much faster once restored to full working condition. By the way, this app removes up to 74 GB of junk on an average Mac computer. So, give it a try — you can download CleanMyMac X for free.

The differences between Internet Recovery and regular Recovery

Normal Recovery Mode accesses Recovery HD, an emergency cache of essential utilities that is saved to a partition in your Mac's startup drive, meaning that it’s kept separate from the rest of your disk space.

Because it’s been partitioned from the rest of your disk space, the data can’t be cleared in cleanup scans or manually deleted. It’s small (650MB) so it won’t affect your Macs performance, but it may be useful if something goes wrong.

If you do need to reinstall your macOS, Recovery Mode will reboot with the most recent version that has been installed on the computer.

Internet Recovery, however, can only reinstall the version of macOS that was originally on your computer when it was new from the box, which likely won’t be the most up-to-date version. This is because Internet Recovery uses code embedded into your Mac that includes an image for the appropriate OS. When you begin Internet Recovery, the image is transmitted to the Apple servers to request the correct codes for reinstallation.

Booting from Internet Recovery takes much longer than a normal partition-based recovery and, naturally, requires an internet connection, so ensure your connection is stable and that you have adequate power (keep your Mac charged).

When to use Internet Recovery

If your Mac has been unable to create a partition for the Recovery HD, you will not be able to use normal Recovery Mode. This might be because you’re using a RAID volume, which doesn’t support the recovery partition, or your drive has been partitioned with Boot Camp Assistant and subsequently modified.

Your Mac may have successfully created the Recovery HD partition but Recovery Mode may not be able to access it. This might be due to damage to the drive or a more serious error in your system.

If your computer is unable to access normal Recovery Mode, it will automatically begin Internet Recovery. If you have a working recovery partition, you will not be able to access internet Recovery Mode.

How To Access Mac Disk Utility

How to enter Recovery Mode on Mac

Hopefully, you’ll never have to use either the normal or internet Recovery Mode for your Mac, but if you do it’s simple to access. For both recovery modes, you will need enough power to see you through the process as well as your Apple ID to reinstall macOS.

1. To start your Mac in Recovery Mode, first, if your Mac is turned off, switch it on. If you’re currently using it, hit Restart. You can only use Recovery Mode from the startup drive.

2. As soon as you hear the startup chime, hold Command (?) + R.

You will need to hold the keys until a new screen appears.

3. If you have a working recovery partition, you will enter the normal Recovery Mode. The macOS Utilities window appears, which will list the four options to recover your Mac (Restore, Reinstall, Get Help, and Disk Utility). Select Reinstall macOS.

From there, your Mac will be cleared and rebooted with the latest version of macOS that had been installed on it.

How to access Internet Recovery Mode

1. Turn on your Mac or restart it as with normal Recovery Mode. As soon as you hear the startup chime, press and hold Command (?) + Option (?) + R.

If your normal Recovery Mode isn’t available, pressing Command (?) + R should automatically redirect you to Internet Recovery mode.

2. After a few seconds, a globe will appear onscreen with the text: Starting Internet Recovery. This may take a while.

Note: This is your computer entering internet Recovery Mode; it is not yet reinstalling OS X.

3. You will then be given a network list to choose your internet connection for the download. Press the check mark to continue or hit Enter once you have selected your network.

4. You will be asked to resubmit the network password even if you have previously connected to it, so make sure you have it available. Hit Enter or the check mark symbol to continue.

5. The screen will then show the image of a globe again, as well as a status bar. This is your computer sending the information about its original state to Apple to request the appropriate drivers and may take some time depending on your internet connection.

6. Once complete, you will see the same Utilities screen as the regular Recovery Mode, which gives you the same options to restore your system.

Mac Recovery Mode: A last resort

It is always worthwhile to run a Disk Utility scan if possible before reinstalling your macOS. It’s even better to keep your Mac maintained with regular scans for issues that can accumulate to cause problems. Give your Mac a complete tidy up before restarting in Recovery Mode. Clean out the junk, declutter and restore your beloved Mac to full health.

Caches and system junk quickly build up to clog your system and cause performance problems that might lead you to believe you need to reinstall your macOS, when really all it needs is a thorough clean-out. CleanMyMac X has cleared 737 million GB of junk files that wear down your system and uninstalled 10.5 million unnecessary applications and their forgotten extensions.

CleanMyMac X can also run diagnostics without entering either Mac Recovery Mode, meaning you can fix operating issues before you need to initiate a full reinstall.
