Part I: Why isn't my hard drive showing up mac

You might be panicking right now because your external hard disk drive cannot be recognized by your Mac device. But you really don’t have to go crazy.

Most likely, nothing has happened to your files within the external HDD. All of it will still be intact within the storage device. But, whatever the reason may be, you simply cannot access these data.

Lucky for you, there are methods you can implement in order for your Mac device to recognize the external HDD and keep you back on your feet. Let’s get started onto why your HDD or flash drive isn’t showing up on your Mac device.

Part II: Reasons For HDDs Not Showing Up On A Mac Device

There are cases wherein you plugged your hard disk drive or flash drive on your Mac and the device cannot recognize it. This could be caused by a broken cable or a faulty USB port. Before you delve into some methods for troubleshooting your system, you should begin with the basics first.

First, you have to make sure that the hard disk drive is really plugged into the device. It might not be plugged properly. After which you have to notice the structure of your USB connector. Is it damaged? Is it misshapen? Ensure that the cable is in perfect condition. There might be exposed wires or it might be frayed.

If you plug your external hard disk drive into an outlet, you should try a different one. It might be the wall outlet that’s faulty. You can also try using another USB cable. The USB cable might be broken even though it’s not obvious or physically damaged.

You can also opt to plug the external HDD to another Mac device. If it works on other Mac devices, your USB ports on the previous Mac might be broken. There might be cases wherein your hard disk drive is formatted to work on Windows computers.

That’s why you should test it out on a laptop or computer with Windows in it. It might be possible that your hard disk drive is formatted to work on Windows PCs and not on Mac devices.

Another thing you can do is to simply turn off your Mac device and turning it on again. Simple rebooting can do wonders on your Mac. You can also try to reboot USB drives.

First, turn off your Mac device, after which, restart it. While in the process of restarting, hold the keys CMD + P + R + Option. Release the said keys when a sound comes up and the screen flashes. Then, let your Mac devices boot itself up as it normally would.

If you have done everything that we have listed above-- inspected your device visually, tested the hard disk drives on different power outlets, cables, and computer devices, and implemented various systems-- and nothing happened, then it’s high time to follow our guide below:

Part III: Methods To Help Your Mac Device Recognize The HDD

There are different ways to let your HDD show up within your Mac device. The first thing would be to modify the settings of Finder. The next would be mounting the external HDD on your Mac device and so on. Let’s get started with the first one:

Method 01: Modifying Settings Of Finder

There is one common reason why Mac doesn’t display or recognize external hard disk drives. The reason we’re stating here is the state wherein the Mac device’ system is not set up to actually show hard disk drives within its Desktop.

This can be fixed easily by following the steps below:

  1. Launch a Finder window.
  2. Visit the Preferences.
  3. After which, visit General.
  4. Make sure that the feature External disks are activated.

But what if it doesn’t work after you have done this? Well, the next thing you should do is to mount the external hard disk drive manually on your Mac device.

Method 02: Manually Mounting Your External HDD Within The Mac Device

If Mac still doesn’t recognize the external hard disk drive you plugged into it, the next thing you should do is to force it to recognize the said storage item. Here are the steps you should follow:

  1. Go towards System Preferences.
  2. Visit Disk Utility.
  3. Examine if the external hard disk drive is shown on the sidebar towards the left.
  4. Select the hard drive and make sure it is highlighted.
  5. Choose Mount. Now, the hard disk drive should be seen within the Finder window under Devices.

Again, what if forcing your Mac drive to display the external hard disk drive doesn’t work? Well, the next step is to utilize First Aid.

Method 03: Running First Aid Through Your External HDD

Mac has a built-in utility called First Aid. This is utilized for the verification and repairing of a wide variety of issues especially with those that are related to apps and files that are corrupted. It also fixes issues with regards to startup and of course, external hard disk drives.

The steps below are for one type of issue. This issue is with that of a hard disk drive that is displayed on your Mac but doesn’t give you access to data. First Aid would be the tool you would use if you have to fix this issue. Simply follow the steps below:

  1. Visit System Preferences.
  2. Launch Disk Utility.
  3. Make sure the external hard disk drive is highlighted or selected.
  4. Press First Aid.
  5. Choose Run. This will now start the process of diagnosing the Mac for any issues and fixing the corresponding problems.

If your attempt to fix this problem with First Aid is a success, your hard disk drive would now be available for mounting. If this doesn’t work again, you should try the option below:

Method 04: Removing Incompatible Or Conflicting Applications

Did you experience the problem of not having an external hard disk drive show up just recently? If it was okay a few days before (just a couple of days), then the problem might be with an application that is in conflict with it.

Think about it. Have you downloaded and installed apps just recently? These might be culprits. What you can do is to uninstall or remove these programs one by one.

Connect your hard disk drive towards your Mac device after you uninstall each program. Check out which app is causing conflict.

You can simply delete these applications by utilizing Launchpad. Or, for a very simple process, you can drag these apps towards the Trash Bin. However, we do not recommend each of the two methods.

It’s because of the fact that even when an app is deleted, leftovers and associated files are still kept intact in your system. These leftover files might be the ones preventing you to access the hard disk drive.

What we do recommend is for you to useFoneDog’s Mac Cleaner. It has a module called Mac Uninstaller that you can use to uninstall applications without leaving any leftover behind. Here are the advantages and the steps to use the tool:

* It gives you the ability to make your Mac device perform faster by freeing up more space within the said device.

The Mac Cleaner helps you delete unnecessary applications without leaving any leftovers behind. Plus, it helps in securing redundant searching history. Finally, it helps in the management of extensions, shredding of files, and cleaning of browsers.

* All of the features of the Mac Cleaner can be implemented with just a few clicks.


* Scanned results of the Mac Cleaner can be sorted on a variety of factors including date, time, size, etc.

* The Mac device status is displayed by the device including disk usage, CPU status, memory usage, etc.

Method 05: Disk Permissions Repair

Disk permissions are very important in keeping your files safe and secure. Every single file and folder within your Mac device has permissions associated with it. But sometimes, these permissions can become messed up.

You won’t even realize it. These messed up permissions can lead to a big problem. You can actually fix this on your own using a tool for repairing permissions.
