Summary
Learn how to recover data from your external hard drive on your Mac, from simple methods like checking the Trash to utilizing professional data recovery software. Protect your valuable files and safeguard against future data loss with these tips.



Have you accidentally deleted important files from your external hard drive on your Mac? Don’t worry, you’re not alone. With the increased use of external storage devices, it’s common to encounter data loss due to human error or technical issues. Fortunately, there are ways to recover data from an external hard drive on your Mac. In this chapter, we will guide you through the first step of the recovery process – checking the Trash Bin for accidentally deleted files on Mac. So, let’s get started and retrieve those lost files!

Step 1: Check the Trash Bin for Accidentally Deleted Files on Mac

If you have accidentally deleted files from your external hard drive on Mac, the first place to check for their recovery is the Trash Bin. In a Mac system, when you delete files from an external hard drive, these files are moved to a folder named .Trash on the external hard drive, which is the trash bin of the external hard drive. These files are not moved to the trash bin of the Mac system. Therefore, if you want to completely delete these files, you need to empty the trash while the external hard drive is connected.
To check the Trash Bin for deleted files on Mac, follow these steps:
Step 1: Open the Trash Bin on your Mac by clicking on the Trash icon in the Dock or by searching for “Trash” in Spotlight.
Step 2: Once the Trash Bin is open, look for the files you want to recover. You can use the search bar at the top-right corner of the window to search for specific files.
Step 3: If you find the deleted files, select them by clicking on them while holding down the Command key.
Step 4: Once the files are selected, secondary-click (or right-click) on them and choose “Put Back” from the drop-down menu. This will restore the files to their original location on the external hard drive.

Step 5: Alternatively, you can drag the selected files from the Trash Bin and drop them onto the external hard drive to restore them.

Note: This method will only work if the Trash Bin has not been emptied while the external hard drive was still connected to your Mac. If you have already emptied the Trash Bin, move on to the next step to try and recover your deleted files from the external hard drive on Mac.

In case the deleted files are still not restored after following these steps, it is possible that they have been automatically removed from the Trash Bin. By default, the Trash Bin on Mac automatically deletes files after 30 days. To ensure successful recovery of deleted files from an external hard drive on Mac, it is important to check the Trash Bin as soon as possible after deletion.
Checking the Trash Bin for accidentally deleted files is the easiest and most common method for recovering data from an external hard drive on Mac. However, it is not always guaranteed to work if the Trash Bin has been emptied or if the deleted files have been automatically removed. In such cases, using Time Machine for data restoration is the next best option.

Step 2: Utilize Time Machine for Easy Restoration of Lost Data

If you have accidentally deleted or lost important files from your external hard drive on Mac, don’t worry. Time Machine, a built-in backup feature on Mac, can help you easily restore lost data. Follow these steps to utilize Time Machine for data recovery.
Step 1: Open the Finder and navigate to the folder where the photos were stored.
Step 2: Click on the Time Machine icon in the menu bar and select “Enter Time Machine“.
Enter Time Machine MacOS

Step 3: Use the timeline on the right side to go back to a date when the photos were still available.

Use the up and down arrow or the timeline on the right to find the date with the desired photos.
Step 4: Select the photos you want to restore and click on the “Restore” button.
With these simple steps, you can easily recover your lost files from an external hard drive on Mac.
Once you have successfully restored your lost files using Time Machine, it is important to take preventative measures to avoid data loss in the future.

Step 3: Use Disk Utility's First Aid to Repair External Hard Drives

Disk Utility’s First Aid is a built-in solution on Mac that can help repair simple corruption problems on external hard drives. This can be a useful first step in recovering data from a faulty external hard drive.
To use Disk Utility’s First Aid, follow these steps:

It is important to note that Disk Utility’s First Aid may not be able to fix all types of external hard drive issues. If your external hard drive is still faulty, you may need to try using the FSCK command in Terminal.

Step 5: Professional Data Recovery Services for Complex Situations

While some data loss situations can be easily resolved using data recovery software, there are more complex cases where professional help is needed. This is where data recovery services come into play. In this chapter, we will discuss the importance of professional data recovery services and how they can help you recover lost data from your external hard drive on Mac.
Understanding the Scope of Work for In-Store Data Recovery Services
Before seeking out professional data recovery services, it is important to understand what kind of data loss situations they can handle. In-store data recovery services typically focus on recovering deleted photos, music, and files from a working drive, or data that was lost due to reformatting. However, it is important to note that not all data loss situations fall under the scope of in-store data recovery services. More severe cases may require higher levels of data recovery, which may not be possible at an in-store location.
Knowing When to Seek Professional Help for Severe Data Loss Cases
However, if your external hard drive has severe issues such as hard drive corruption with bad sectors, physical damage, or unusual noises, it may be time to seek professional help. In these cases, attempting to use data recovery software may not be effective and may even cause further damage to your hard drive.
Choosing Reliable and Secure Data Recovery Services
When selecting a professional data recovery service, it is important to choose one that is reliable and secure. EaseUS, for example, offers a team of experts who can provide one-on-one manual data recovery services if your hard drive has physical damage. It is also essential to check the data recovery cost and reviews to ensure you are choosing a trustworthy and reputable service.

Strategies for Preventing Future Data Loss on External Hard Drives

External hard drive data loss can be a frustrating and stressful experience, but it can be avoided with proper preventive measures. In this chapter, we will discuss various strategies that can help prevent future data loss on external hard drives.
Eject the Hard Drive Correctly
One of the simplest and most important ways to prevent data loss on external hard drives is to always eject the drive correctly.

By having a backup of your data, you can easily retrieve it in case of any data loss on the external hard drive.
Protect Against Physical Damage
Physical damage is one of the leading causes of data loss on external hard drives. To prevent this, always handle the hard drive with care and avoid dropping or mishandling it. Additionally, make sure to keep the hard drive in a dry and dust-free environment and use a protective case while transporting it.
Seek Professional Help for Complex Situations
If your external hard drive has suffered physical damage or the data loss is too complex for DIY recovery software, it is best to seek professional help. Data recovery experts have the necessary tools, knowledge, and experience to retrieve data from severely damaged or corrupted hard drives. They also follow proper procedures to avoid further damage to the hard drive while recovering the data.
