Whether you’re the victim of an accidental reformatting or a corrupted drive, it can be heart-wrenching to think of losing all your precious data forever. The special moments captured in family photos. The vital tax documents. The work-related spreadsheets. And yes, even the saved game files on which you spent far too much time.
But luckily, a formatting error doesn’t mean your data is gone for good. There are a few simple steps you can take to get your files back—permanently.
This guide presents the three top options for recovering data from a formatted Mac hard drive. If you’d prefer to skip the theoretical explanations and proceed directly to the recovery guide, click here.
Recovering a Formatted Hard Drive on Mac: Is It Possible?
The short answer here is yes, you can recover a formatted hard drive on a Mac.
When you format a hard drive, you’re preparing it to use a specific file format system. On the surface, this process erases all of the information on the drive—a terrifying prospect if you aren’t expecting it.
However, your data isn’t actually gone here as long as:
- you used quick formatting rather than full formatting (default on macOS);
- if you’re using an HDD (things get a bit trickier on SSDs thanks to TRIM, which deletes data permanently to boost performance).
Instead, it’s more like the process makes your information invisible. It’s only after you write new data over the existing data is your information lost completely.
Recovering a formatted external hard drive on a Mac is often the most common scenario and tends to be the easiest to handle. For a deeper understanding of recovery complexities associated with different drive types, refer to our Understanding Drive Types and Their Recovery Complexities section.
As a result, you can recover those “lost” files. However, to do so successfully, you need to follow these steps to increase your chances of recovering files from an erased hard drive on a Mac.
- Immediately stop using the drive. Every moment you continue to write new information to that drive, your chances of recovering your lost data are less and less.
- Find a data recovery solution. This guide outlines four of the best solutions out there (three that are software and one that’s a service). More on those in a bit.
- Cross your fingers. As long as you don’t use your hard drive immediately after formatting, chances are good you can recover your data. But some factors, like your hard drive type, can end up making recovery impossible.
Basics of Hard Drive Formatting: A Quick Guide
To better understand how you can recover files from a formatted hard drive on a Mac, it’s best to get a basic grasp of what formatting means.
In most cases, formatting a hard drive refers to creating or changing a drive’s format system. All drives need a format system. Simply put, the format is the specific way information on the drive is organized. Without that system of organization, the data won’t make any sense to the system reading it.
Different operating systems can read data based on specific file systems. Modern Macs are compatible with three file systems: Apple File System (APFS), Mac OS Extended (HFS+), and MS-DOS (FAT) & exFAT (also compatible with Microsoft).
As a result, you may find yourself needing to reformat a drive to make it compatible with your Mac. Fixing a corrupted hard drive may also mean you need to reformat. And you may have even reformatted your drive entirely by accident.
Regardless of the reason for formatting, you can potentially retrieve your files, as they aren’t truly gone until new data is written on the drive.
How to Recover Files From a Formatted Hard Drive on a Mac
There are a few ways to recover deleted files on a Mac. But when it comes to getting your data back from a formatted hard drive, your best bet is to use third-party software to get your data back (a.k.a, “unformat your Mac hard drive”). Don’t worry—it’s not as scary as it sounds.
Below are the three best options we’ve found for formatted Mac hard drive recovery.
Option A: Disk Drill for Mac
Disk Drill is without a doubt our go-to option if we want to recover files from an erased hard drive on a Mac. Among the best data recovery software options out there, Disk Drill is remarkably simple to use. And it boasts an impressive 90% recovery rate—not bad at all.
This data recovery software is free to use and capable of recovering hundreds of file formats from storage devices. Whether your drive is formatted, corrupted, or even perfectly healthy, Disk Drill is an excellent tool for data recovery.
Dive deeper into the specifics of Disk Drill by exploring our in-depth review. We also have a separate article focusing on the safety analysis of Disk Drill; however, our reviews are based on the Windows version. If you’re keen on learning more about the macOS version, we recommend these articles: review #1 and review #2.
To recover your deleted files from a formatted Mac hard drive using Disk Drill:
- Download Disk Drill and install it on your Mac by dragging the icon to the Applications folder.
- Launch Disk Drill and grant it full disk access (required if you want Disk Drill to find your lost files).
- Choose the formatted hard drive you want to scan and click the “Search for lost data” button to start the scan.
- Wait for the scan to finish. It may take several minutes, depending on the size of your drive.
- Click “Review found items” to view the found files (or click “Recover all” to relocate everything found on the drive).
- Find the files you’re looking for. Click the eye icon next to the files to preview them.
- Select the files you want to restore and click the “Recover” button.
- Choose the destination you’d like to restore them to and click the “OK” button. Make sure you don’t restore to the same drive to avoid overwriting the data.
Option B: PhotoRec
PhotoRec is another data recovery software option. It’s completely open-source, which means you won’t have to pay to use it. You’ll have to download and install two additional pieces of software to access it though, Homebrew and TestDisk.
It also doesn’t have a graphical interface (maybe a turn-off for some). But rest assured, it’s a snap to navigate.
Take a look at our detailed review on PhotoRec to learn more about using this recovery software.
To recover your files from a formatted Mac hard drive using PhotoRec:
- Install Homebrew by navigating to Terminal (Command + Space, then type “Terminal”). Then copy and enter this command:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" 2> /dev/null
You may need to enter your Mac user password. Do so and hit Enter (your screen will not show your password as you type as a security measure).
- Enter the following command to install TestDisk:
brew install testdisk
- Run PhotoRec by entering the following command:
- Choose your drive from the populated list. If your formatted disk is not showing, check that it’s correctly connected to your Mac and relaunch PhotoRec.
- Select the type of file format that the storage device uses.
- Select the location you’d like to save the deleted files. You can’t select the individual files on the drive, so be sure you put them in a location that’s easy to navigate, as PhotoRec will recover all the files it finds.
- PhotoRec will then start recovering your missing files. You’ll receive a notification when the process is over. You’ll also be able to see how much of your data PhotoRec was able to recover. After that, head to the location you selected, and your recovered files will be there, good as new.
Option C: EaseUS Mac Data Recovery Software
Another option to recover an erased hard drive on a Mac is EaseUS. Featuring a smooth graphical interface, plenty of compatible file types, and yes, a free option, EaseUS is a favorite for data recovery.
That being said, you’re limited to 2GB of recovered files with the free version, which may be less than some users hoped. The paid plans may also be out of some people’s price range.
We’ve talked about EaseUS before. And if you want to get a better idea of how this recovery software stacks up, take a look at our comprehensive EaseUS review here.
To use EaseUS to restore a formatted hard drive on Mac:
- Download and install EaseUS Data Recovery Wizard. You’ll want to make sure you’re downloading the “Free” version rather than the “Trial” version. The free version lets you recover up to 2GB of files. With the trial version, you’ll need to upgrade to a paid plan to recover any files.
- Grant EaseUS permissions to access your drives (required for data recovery).
- Choose the formatted drive you’d like to recover files from and click the “Scan” button.
- Wait for the scan to complete. It may take a while, depending on the size of your drive.
- Drill down through the file locations to find the files you’d like to recover. You can double-click the files to generate a preview. After you’ve chosen your files, click the “Recover Now” button.
- Choose where to save your recovered files and then click the “Save” button. Your files will then transfer to that location where you can interact with them like usual. Remember, you’re limited to restoring just 2GB of files using EaseUS Data Recovery Wizard.

Understanding Drive Types and Their Recovery Complexities
The process and success of data recovery can vary significantly depending on the type of drive and the specific circumstances surrounding its formatting:
- External Hard Drives: Recovery from external hard drives is generally straightforward. If you’ve formatted an external hard drive, follow the recovery instructions provided in this article.
- Internal Hard Drives (Non-system partition): The process for recovering data from a non-system partition of your Mac’s internal hard drive is similar to that of external drives.
- Entire Internal Hard Drives: Although it’s uncommon, it’s possible to accidentally format your Mac’s entire internal hard drive. Such a scenario presents a more intricate recovery challenge. If you’ve already re-installed macOS post-formatting, you can still follow the recovery guidelines in this article. However, be prepared for the possibility that some old data may have been overwritten during the OS reinstallation. If you haven’t reinstalled macOS after the accidental format, you can:
- Boot from Another Device: Use an external drive with macOS installed to boot your Mac, allowing access to your internal drive without adding new data.
- Use Your Internal Drive Externally: By connecting your Mac’s internal drive to another computer as an external drive, you can access and attempt data recovery without risking further overwrites.
Regardless of the situation, if you’ve formatted the entire internal drive, it’s strongly advisable to seek consultation or services from data recovery professionals. Their expertise and tools can significantly enhance the likelihood of successful data retrieval.
