Symptoms of a Hard Disk Problem

The worst noise you’ll hear from a mechanical hard disk is a clicking or grinding noise. That means the drive is failing. At that point, the drive isn’t repairable. It’s time to back up your data and then replace the drive. You already have a backup though, right?

Not all drives exhibit symptoms in this way. Sometimes you’ll get the prohibitory no symbol at startup or a flashing folder with a question mark. After turning off your Mac and turning it back on, the system boots just fine. Other times you’ll get the spinning rainbow wheel, letting you know your Mac is waiting on something. That could be because your Mac is waiting on the hard symbol at startup or a flashing folder with a question mark. After turning off your Mac and turning it back on, the system boots just fine. Other times you’ll get the spinning rainbow wheel, letting you know your Mac is waiting on something. That could be because your Mac is waiting on the hard drive.

Sometimes it isn’t the Hard Disk

If you’ve tried all this and are still having problems, there could be something wrong with your Mac other than the hard drive. If you have a MacBook Pro, the ribbon cable that connects the hard drive to the rest of the computer can go bad. The Mac exhibits all the same symptoms as a failed hard drive. The best way to figure this out is to remove your hard drive and try it in another Mac. If the hard drive works on another computer, then it isn’t your hard drive.

The Disk Utility application is a powerful tool for keeping the drives that are connected to your Mac happy and healthy. But there are situations in which it may not be available. As an example, connecting to a remote computer via SSH, or Disk Utility simply refusing to launch.

In this tutorial, I’ll show you how to:

  • Find a disk that may have an error
  • Verify a disk from the command line
  • Repair that disk (if need be) from the command line


Important Notes

Before I take you any further, you need to understand a couple of things:

  1. I will be working on an SD Card I have inserted into my mac. If you need to target your Mac's hard drive, make sure you substitute the word Macintosh HD for SD in any of the commands I am showing in this article.
  2. These instructions are not meant for novice Mac users. If you aren't at least a bit comfortable in Terminal, you may want to stick to the graphical user interface applications like Disk Utility.

Locating the Disk

All of the disks that are attached to the Mac are located within the Volumes directory in Terminal. This directory is located one step away from the root of the Mac. The command used to switch from directory to directory is cd. In the terminal a /is known as the root, or lowest level, directory.

So to switch to the Volumes directory, open Terminal and type or paste in this command: cd /Volumes. The Terminal window should now look very similar to this:

Type ls and press Return. You’ll be shown a list of disks attached to your Mac.

Verify the Disk

Once you have the list of disks, you can target one or many of them for verification and repair. To start the verification process, type the following command, while being sure to substitute the [drive identifier] portion for the actual name of the drive.

diskutil verifyVolume [drive identifier]

If you are targeting the Mac's hard drive you can also simply use a /. You will see something that looks like this:

This test came back successful. So I can be confident in the drive and its ability to store data. If there was an error I would see a message that reads: The volume [volume tested] was found corrupt and needs to be repaired.

Repairing the Disk

Assume, for a moment, that the disk did come back with an error or needing repair. To repair a disk from the command line, type or paste the following command into terminal: diskutil repairvolume /Volumes/[drive identifier]/ and press Return.

Just as before, I’ll use SD as my drive identifier. If you wish to target a different drive, insert the name of that drive instead of SD. You may also use / as the identifier for your Mac's hard drive. Your Terminal window should now look similar to this:
