How to recover files from an external hard drive on Mac

Here are four solutions to recovering deleted or lost files from an external hard drive.

Honorable mention: Restore from the Trash Bin

One thing that’s great about macOS is that deleted files are first moved to the Trash folder, including files deleted from an external hard drive. We know that you’ve probably done so already, but we strongly suggest you check the Trash folder one last time before exploring the three main solutions described below. 

  1. Make sure the external hard drive is connected to your Mac. Each Mac storage device has its own Trash folder, so this step is critical.
  2. Open the Trash folder by clicking on its Dock icon.
  3. Locate the files you want to restore and select them.
  4. Right-click on your selection and click the Put Back option.recover deleted files external hard drive mac by trash bin
  5. Verify that the files have been successfully recovered to their original location.

Unfortunately, there’s no guarantee that your files will be present in the Trash folder, especially if the option to automatically remove items from the folder after 30 days is enabled on your system. If that turns out to be the case, then it’s time to explore other recovery solutions.

Solution 1: Restore from a backup file

The best way to recover files from an external hard drive on a Mac for free is through a backup copy you have previously created. Here are several places to look for a backup copy:

  • External storage devices: USB flash drives, memory cards, and other external storage devices are commonly used to store backup copies of important files, and there’s a chance that a copy of the files you want to recover from your external hard drive exists on one of your devices without you even realizing it. If you find it, you can simply copy your files to their original location and congratulate yourself for remembering to back up your data at some point in the past.
  • Cloud backup services: More and more users these days back up files to cloud backup services like iCloud, Dropbox, Google Drive, or Microsoft OneDrive. Files stored in the cloud can be recovered from anywhere and any device because they’re located on a remote server managed by a third party. This alone makes them perfect for recovering data lost due to, for example, a hardware failure or natural disaster.
  • Native backup features: Modern operating systems are equipped with native backup features whose purpose is to help users protect important files. To be more specific, Macs running macOS 10.5 or newer come with Time Machine, and this native backup feature can be a real lifesaver if you need to recover data from an internal or external hard drive on Mac.

To restore from a Time Machine backup file, you need to:

  1. Connect the device that contains the Time Machine backup to your computer.external hard drive data recovery mac from time machine backup
  2. Open a window that displays the folder which contained the deleted file. For example, if you deleted something from Downloads, open a Finder window of the Downloads folder. 
  3. Open Time Machine by clicking on the clock icon on Mac’s menu bar and select Enter Time Machineexternal hard drive data recovery mac from time machine backup
  4. Locate the items you want to restore from within Time Machine.
  5. Select an item and press the Spacebar to preview it.
  6. Click Restore to recover the selected file or folder.external hard drive data recovery mac from time machine backup

Since macOS 11 Big Sur, Time Machine also supports the APFS file system, making it faster and more reliable than was previously possible with HFS+-formatted drives. Just know that there are several requirements your backup drive must meet in order to work with Time Machine, and you can read more about them on Apple’s website

Pros

  • The backup tool is freeware that is included with your Mac computer.
  • It recovers files that have been permanently deleted from the Trash Bin.

Cons

  • This method requires you to have created a backup of the affected files.

Most Common External Drive Data Loss Causes

Data can be lost on an external drive for a variety of reasons:

  • Human error – Accidentally deleting files or formatting the wrong drive is the most common reason that data is lost from external storage devices.
  • Malware – Malicious software is another common cause of data loss. Infection with viruses can lead to file corruption and randomly deleted files.
  • Physical damage – Over time the physical disk performance may degrade and result in deleted files and folders.
  • Theft – External hard drives are subject to being stolen because of their portability. While no data recovery technique will resolve this issue, it should be taken into consideration when using these types of devices for important or sensitive information.

Protect your External Hard Drive From Accidental Data Loss

You can take several steps to protect the data on your external hard drive.

  • Make backup copies of the data on the external hard drive. This is considered best practice for any type of storage device. Backups are your best protection against all types of data loss scenarios.
  • Keeping an external hard drive away from potential virus infection is critically important. You may have good antivirus software running on your computer, but you don’t know about your friend’s machine. Avoid connecting your drive to any strange machine to avoid potential infection.
  • Double-check your work before performing data deletion or formatting an external hard drive. It may save you time later if you end up needing to perform a recovery.
  • Secure your external hard drive physically to keep it safe and out of the hands of a potential thief. It’s not paranoia. Someone might steal it if they got a chance.
