Recover data from external hard drive on Mac

Data loss these days is rare. With local device storage, external hard drives, and cloud backups, our data is usually in more than one place. However, data loss can still happen and it’s important to know how to recover data in the event that we have lost important information.

In this article, we’re going to look at how to recover data from an external hard drive on Mac and other methods that can be used to get data back after it has been deleted.

Best Methods to Recover Data from External Hard Drive on Mac

The first thing that we need to do is make sure that our Mac can recognize our external hard drive as we can’t start data recovery without our Mac being able to see it. If your external hard drive is showing up already, then you can move on recovering data from an external hard drive

Method 1: Recover Files by Checking the Trash

When you delete a file on your Mac or your external hard drive, it will go into the Trash. The trash is in place to make sure that you have an extra layer of security when deleting files from various storage devices.

Recovering files from your Trash is super easy and the files will stay there forever unless you have your Trash set to empty on its own. If you want to set your Trash to empty on its own, you can do so by going to your Finder preferences.

In the steps below, we’re going to look at how to recover files from the trash which only takes a couple of steps and is super easy to do.

Step 1. Click the Trash icon on your dock.

Step 2. Once you have opened your Trash, select the files that you would like to recover. After you have selected them, right-click on them and choose Put Back.

The files will then be put back to the original place that they were before they were deleted. Most of the time, this is the method that you will be able to use to recover files, and trying to access your external hard drive won’t be necessary.

If you have already emptied your Trash or have it set to empty after 30 days, then we can move onto Time Machine as the next method for recovering data from your external hard drive.

Method 2: Recover Files Using Time Machine

Every Mac comes with Apple’s built-in Time Machine tool which allows us to take a look into our external hard drive and recover files and put them right back onto our Mac.

Step 1. Plug-in your external hard drive.

Step 2. Launch Finder and then open Time Machine.

Step 3. Once within Time Machine, we can recover files from an external hard drive on Mac by either using the up and down arrows or use the date slider at the lower right-hand side to scroll through different dates and times.

Step 4. Simply find the date that you think that you last had the data that you’re wanting to recover, and then navigate through the Finder and locate the file. You can then click on Restore and put that file back onto your Mac.

Time Machine is great because it’s easy to understand, takes only a few steps, and has a graphical interface that isn’t cluttered with things that don’t need to be there.

Method 3: Use Data Recovery Software

Disk Drill allows us to recover data from an external hard drive. If the external hard drive isn’t working or if you accidentally deleted a file off of it, we can scan the drive and try to find the data that was lost. If you’re wondering “How do I recover files from an external hard drive that’s not detected?” sometimes Disk Drill may be able to see the external hard drive, even if Time Machine can’t.

Step 1. Launch Disk Drill.

Step 2. Select your external hard drive as the device to scan.

Step 3. Wait for the scan process to complete.

Step 4. Browse through the contents and checkmark the items that you would like to recover. You will then want to click the blue Recover button in the lower right-hand corner of the screen.

That’s it! Disk Drill is great at helping you recover files from an external hard drive if you can’t find them on the drive or if the drive is failing.

What if My Mac Can’t Recognize My Hard Drive?

If you plug your external hard drive into your Mac and nothing happens, don’t worry the drive most likely isn’t broken. There are some steps that we can take to try and get the external hard drive to be recognized.

Do keep in mind though, that external hard drives can fail even though it is not likely. They’re mechanical devices with moving parts which over time, can stop working if they have been subjected to damage or have failing components.

Before we come to that conclusion though, here are some ways to try and get your external hard drive to mount to your Mac.

Fix 1: Restart Your Mac

As cliche as it may sound, restarting your Mac can fix a lot of issues on its own. The simple “turn it off and back on again” is a good way to troubleshoot issues and should allow for the hard drive to mount to your Mac.

Step 1. Unplug your external hard drive from your Mac.

Step 2. Restart your Mac.

Step 3. Once your Mac has booted back up, plug in the external hard drive and see if it is functioning correctly.

Fix 2: Check Your External Hard Drive’s Connection

The issue could also be something as simple as the cable that you’re trying to use to connect the hard drive to your Mac. Cables do fail, if you have a spare around, try using that instead and see if that fixes the issue.

It could also be the port on your Mac. Try plugging the external hard drive into another port and see if the hard drive mounts to your computer.

Lastly, if you’re using an adapter or dongle try plugging the external hard drive right into your computer and see if that fixes the issue. If you need the dongle due to a connector compatibility issue, try using a different dongle or plug it into another computer.

Fix 3: Reset NVRAM

NVRAM in short, stores settings that you have made on your Mac. It won’t change the configuration of your System Preferences, but it stores things such as sound settings, time zone information, and settings related to hard drives.

Resetting your NVRAM could solve the problem of your hard drive not being recognized by your Mac and it only takes a few steps to reset it.

Step 1. Shut down or restart your Mac.

Step 2. Once your Mac starts back up, immediately press and hold Option, Command, P, and R all together at the same time.

Your Mac will then start back up again and you can let go of the keys at this point. Check and see if the external hard drive is now being recognized by your computer.

When I worked at an Apple Store, this would fix common issues for customers and it is a simple way to troubleshoot why your external hard drive may not be mounted to your Mac.

Fix 4: Repair the External Hard Drive Using Disk Utility

If external drive is present in Disk Utility you can repair it using the First Aid. First Aid can find and repair errors related to the formatting and directory structure of the external hard drive which could increase the chance of external hard drive data recovery on Mac.

Step 1. Plug-in your external hard drive.

Step 2. Launch Disk Utility and find the external hard drive.
