Hard Drive Recovery on Mac: Recover Files from Internal or External Drives

It can be a challenge to recover data from a Mac hard drive. That’s why we have developed an easy-to-use data recovery tool called Disk Drill. Our tool is designed to quickly and efficiently retrieve lost files from all internal and external drives, even on macOS Sonoma. We also describe several other methods you can use to rescue your data or repair your hard drive.

How to Recover Data from Mac Hard Drive

Depending on the extent of the damage and its nature (physical vs logical), You might find that you can see some files and folders on your hard drive, or you might encounter issues like unpartitioned, formatted, or corrupted disks. The good news is that Disk Drill can find lost partitions, rebuild HFS+ catalog files, and do other things to help you recover your lost data as long the drive in question is able to spin up and communicate with your computer (is visible in Disk Utility).

Here's a quick overview of the steps for using our Mac hard drive recovery software, Disk Drill.

!

Note: It's important to note that for macOS 10.13 and newer, enabling system extensions (called kext) is necessary to recover files from system drives, such as the main disk housing your macOS. Also, disk physical damage may substantially lower the success rate of the hard drive recovery.

Follow these Steps to Recover Deleted Files from Mac Hard Drive

1. Download and Install Disk Drill for Mac

Before you download Disk Drill hard drive recovery software for Mac, ask yourself if you need to recover an external or internal hard drive. It's important to install Disk Drill on a different storage device than the one you are trying to recover from.

Why? Because it prevents overwriting any recoverable data on the affected drive. For instance, if you're recovering files from your Mac's internal hard drive, install Disk Drill on an external drive (drag the Disk Drill icon to a Finder window with a suitable location opened). Similarly, if your external drive needs recovery, make sure Disk Drill is installed on your Mac's internal storage (you can drag Disk Drill to your Applications folder) or another external device.

You can then launch the Disk Drill application and complete the initial installation process. During this process, you will be asked to let Disk Drill access your internal or external drive without any restrictions, which enables it to recover data from a Mac hard drive in the most comprehensive manner possible.

2. Backup your Hard Drive

If your hard drive shows signs of physical damage or extensive corruption (like strange noises, slow read/write operations, or bad sectors), then it’s essential to back it up because the drive could fail at any moment, making data recovery impossible.

Disk Drill includes a free, convenient tool for creating a byte-to-byte backup. This tool generates a comprehensive disk backup image in DMG (or ISO) format, capturing even the sectors that are currently unoccupied but may contain recoverable data. You can select this tool from the left pane (it’s called Byte-to-byte Backup) and then simply tell it which storage device you want to back up.

After creating this backup disk image, you can initiate hard drive recovery using the image instead of the actual hardware. The latter approach is safer as it minimizes the risk of further drive failure during scanning.

!

Note: Disk Drill’s byte-to-byte backup tool is not suitable for internal system drives on Macs with T1, T2, M1, M2, or M3 chips, as these are encrypted with a special chip. Such drives must be scanned directly.

3. Scan your Hard Drive

For this step, open Disk Drill and go to the Storage Devices tab. Here, you'll see a list of all available devices. Select your hard drive from this list. To achieve the best results, choose the entire storage device rather than just a single partition. Once selected, click on "Search for lost data" to start the scanning process. Disk Drill is capable of recovering data from all commonly used types of partitions (see the technical information below for more details).

When it comes to recovering a system drive, Disk Drill will require the installation of a system extension (kext). This extension grants Disk Drill low-level access to your system drive's file system. Without the kext, Disk Drill will be able to only allocate existing data, scan local Time Machine snapshots, and display non-file entries like contacts stored locally on your drive.

If you're attempting to recover data from a TRIM-enabled SSD, be aware that this process involves additional steps. For detailed guidance on SSD data recovery, please refer to the FAQs at the end of this page.

4. Wait Until the Software Finishes Scanning

The duration of the scanning process by Disk Drill varies depending on the type and size of your hard drive. Larger drives or those with slower read/write speeds, like external hard drives, take longer to scan.

During the scan, Disk Drill continuously displays the number of files found to keep you informed of the progress. You have the option to click the "Review Found Files" button at any time to preview the results, even while scanning is still ongoing. You can also pause the scanning process and resume it later. Just know that we guarantee the best results when the scan is completed fully without interruptions.

Wait Until the Software Finishes Scanning

5. Recover From Mac Hard Drive

Once the scanning is complete, you will see the list of found files, and you can narrow them down using filters in the left pane and the top toolbar. Sometimes these files can still be corrupted. This means that another application may have overwritten a block of bits and the whole file structure is lost. Unfortunately, there's no way to prevent this. In reality, data recovery on Mac is mostly about luck! (The one exception to this is Guaranteed Recovery.) Click the "eye" icon next to each name to Preview the file to determine if the file is intact.

When you are ready, select the files and click the "Recover" button. At this point, you will be asked to upgrade to Disk Drill PRO if you haven’t purchased a license already. Make sure the recovery destination is outside of the hard drive you are recovering from. Wait until all the recovered files are copied to the new media.

How To Recover Data From a Mac SSD?

Solid-state drives (SSDs) provide higher access speeds and are used in many newer Apple Macintosh computers. Here is the procedure to use to recover deleted data from an SSD drive that has TRIM disabled. If TRIM is enabled on your MacBook Air, MacBook Pro or iMac, recovery is not possible without a backup of your data. These are the steps you need to follow:

  1. Turn off the Mac as soon as you realize you have lost some data.
  2. Use another Mac to download and install Disk Drill. This will be known as the host machine.
  3. Restart the affected Mac in Target Disk Mode and connect it to the host computer.
  4. Use Disk Drill to create a byte-level backup of the SSD drive to be used to recover its data.
  5. If you cannot create the byte-level backup, scan the affected Mac using Disk Drill from the host computer.
  6. Allow the scanning process to complete and restore the recoverable data that the application has found.

Another option is to create a bootable disk and boot your Mac from it so you bypass the SSD disk. You are trying to preserve the data on the disk, so you don’t want to use it to boot your computer.
