What We Looked for When Choosing the Best Disk Repair Software for Mac?

During our search for the best disk repair software for Mac, we evaluated each tool against a set of key parameters. We selected these parameters based on our extensive, real-world experience with hard drive repair. Here’s a closer look at the parameters we considered:

  • Compatibility with Mac file systems

    Mac computers rely on different file systems than Windows and Linux machines. The default file system of newer Macs is called Apple File System (APFS), while older Macs use Hierarchical File System (HFS+ or HFS Plus). For disk repair software to be useful, it must support all Mac file systems, and, ideally, also Windows and Linux file systems.

  • Overall performance

    This parameter assesses the proposed functionality of the tool and the results of its work.  In other words, it measures how well the software delivers on its promised capabilities. A high-performing disk repair tool should effectively recover data, repair corrupted sectors, and resolve various disk errors.

  • S.M.A.R.T. monitoring capabilities

    Prevention is indeed worth a pound of cure, and S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) monitoring can help you detect emerging hard drive issues well before they become critical. Moreover, S.M.A.R.T. monitoring can potentially help determine the reason behind the problem with the drive.

  • Corruption repair capabilities

    Hard drive corruption and bad sectors can lead to system instability, data loss, and failed read/write operations, often caused by malware, buggy software, or hardware issues. The best disk repair software for Mac can address both issues by detecting and repairing bad sectors and fixing file system inconsistencies, directory issues, and other corruption-related problems.

  • Data protection functionality

    To avoid data loss, it’s paramount to regularly back up all important data. To do that, you may not even need to install dedicated backup software because many disk repair software applications come with built-in data backup and recovery capabilities. Of course, it never hurts to have more than one copy of your files, so don’t hesitate to combine local backups with cloud backups.

  • Data recovery abilities

    The best disk repair tools offer robust data recovery capabilities that enable you to retrieve lost or deleted files caused by various issues, such as accidental deletion, corruption, or formatting. They do this by retrieving file system information, looking for file signatures, or, ideally, both, which allows them to recover even RAW drives.

  • Easy-to-use user interface

    It goes without saying that you don’t want to waste your time on a disk repair application that’s pain to use when there are so many excellent options available. The application of your choice should have a modern user interface that’s easy to understand and doesn’t require you to read a manual just to understand available options.

  • Availability of a free trial version

    The fact is that the best disk repair software solutions are not free—at least not entirely. We say that because many disk repair software solutions offer a free trial version that let’s you play with all key features without spending a single dollar, allowing you to decide whether the software is really worth it or not.

  • Online reputation

    When selecting the best disk repair software for Mac, we considered the software's reputation as an essential factor. To determine reputation, we looked at user reviews and ratings on various review platforms, as they provide valuable insights into real-world experiences and performance.

Attention

We recommend reading our comprehensive reviews to gain deeper insights into each tool's features and performance. Also, don't forget to explore our other Mac and Windows software reviews to stay informed about the best options available. To save time and effort, try our software picker, which will help you quickly choose the ideal tool based on your needs.

Detailed overview

Usability

Disk Drill for Mac is designed with usability in mind. The average Mac user can launch the software, select the problematic hard drive, and click the Search for lost data button. Disk Drill will automatically run its recovery algorithms on the hard drive, select the optimal data recovery method, and proceed to locate deleted and lost files. All that’s left to do is pick the right files for recovery (easy thanks to Disk Drill’s filters and preview feature), and click the Recover button. 

Recovery/repair performance

  • Directory error repair. DiskWarrior specializes in repairing directory errors on Mac computers.
  • Bootable recovery. The software can be used as a bootable recovery tool by users whose Macs are unable to boot into the operating system properly.
  • Disk monitoring. You can use DiskWarrior to monitor the health of your hard drive in order to take action before it’s too late.
Top DiskWarrior Cons
  • Limited file system support. DiskWarrior does not currently support Apple File System (APFS) disks, and it cannot rebuild the Startup Disk of macOS 10.13 High Sierra through macOS Sonoma (14.0) with SSDs.
  • No trial version. The software does not offer a trial version, so users can’t test its capabilities before purchasing.
Detailed overview

Usability

DiskWarrior's user interface is straightforward and easy to navigate, but it does look a bit outdated. Users can quickly select their problematic drive and initiate the repair process. The process of repairing directory errors is automated, with DiskWarrior creating an error-free version of the directory to compare with the original.

Recovery/repair performance

As a tool focused on directory errors, DiskWarrior's strength lies in its ability to rebuild your Mac's directory structure from scratch to eliminate problems and optimize performance. This can lead to significant improvements in how quickly programs scan the directory, potentially reducing scan times by up to 60%. What’s more, DiskWarrior is capability to run from a bootable device and perform repairs even when the main operating system is compromised.

Value

DiskWarrior is priced at $119.95, with a special discounted price of $59.95 for existing customers upgrading from previous versions. While the software does offer unique directory repair capabilities, its limited file system support and lack of a trial version may make it less appealing to users with even slightly modern Macs, all of which come with APFS-formatted hard drives.

Quick overview

Data Rescue for Mac is a data recovery tool with a long history, offering two scan modes to recover deleted files from various storage devices. However, its aging interface and certain limitations affect its usability and performance.

Data Rescue for macOS – Gallery
Top Data Rescue Pros
  • Two scan modes. Data Rescue offers Quick Scan and Deep Scan modes to recover lost files, with Quick Scan being faster and Deep Scan providing more thorough results.
  • Unlimited recoveries. With a single license, users can perform an unlimited number of recoveries from up to 5 drives.
  • Virtual RAID support. With Data Rescue, you can assemble virtual RAID arrays and recover data from them.
Top Data Rescue Cons
  • Barebones user interface. Data Rescue’s user interface is outdated and lacks the polish of more modern data recovery tools, which may make it less inviting for some users.
  • No pause feature. The Deep Scan mode can take several hours to complete, and it’s impossible to pause the scan, which can be inconvenient.
  • System disk scanning limitations. Cannot directly scan system disks on macOS 10.13 and newer without entering Recovery Mode.
  • Internet access is required. Data Rescue requires an internet connection for license validation.
Detailed overview

Usability

Data Rescue's user interface is fairly basic, and it appears that the developers have not focused on making it visually appealing or user-friendly. Despite its simplicity, the software is relatively easy to use, with only a few steps required to initiate the recovery process. However, the lack of a pause feature during scanning means that the software will take up your system resources from the moment scanning begins to its end, unless you decide to cancel it and start again from scratch.

Recovery/repair performance

Data Rescue offers two scan modes for data recovery: Quick Scan and Deep Scan. The Quick Scan mode is faster and can recover recently deleted files, while the Deep Scan mode is more comprehensive and can recover data from formatted or corrupted drives. However, the Deep Scan mode can take several hours to complete and, as we’ve pointed out in the section above, can’t be paused. Even bigger issue is the fact that the software can’t directly scan system disks on Macs running macOS 10.13 and higher; it’s necessary to boot into Recovery Mode first. 

Value

Data Rescue's pricing ranges from $79 to $399, depending on the desired features and the number of drives to be recovered. While the software does offer unlimited recoveries with a single license, its aging interface and limitations make it less attractive compared to more modern data recovery tools with similar or better performance.

Top Drive Genius Cons
  • Limited compatibility. Drive Genius doesn’t support macOS 14 (Sonoma) or later.
  • Outdated user interface. We believe the user interface of this disk repair tool could use an update.
Detailed overview

Usability

The user interface of Drive Genius is organized into three categories: Protect, Clean Up, and Speed Up. This makes it easy for users to navigate and select the appropriate tool for their disk repair needs. Unfortunately, the user interface hasn’t been updated in a while, and it shows. When you launch it on a modern Mac, the app stands out like a sore thumb, and its outdated design doesn’t inspire much confidence in its repair capabilities. 

Recovery/repair performance

Despite its ugly exterior, Drive Genius offers a wide range of disk repair features, including consistency check, repair, rebuild, and hardware issue detection. The software's Instant DrivePulse feature is especially worth mentioning, as it checks your hard drive for hardware-related problems, such as those resulting from a damaged drive, bad cable, or bad connection. Unfortunately, you won’t be able to use these feature if you’re running the latest version of macOS because the last supported version is macOS 13 (Ventura).

Value

Drive Genius offers a professional version available for a one-time payment, starting from $79 to $299, depending on the license type. There’s also a free demo version that allows users to test its compatibility and functionality on their Mac before purchasing. But despite the numerous tools that are included in the software, the overall value isn’t great because you can’t run Drive Genius on the latest version of macOS.

Value

Carbon Copy Cloner offers a 30-day trial and a one-time purchase price ranging from $39.99 to $100, depending on the license type. Considering its powerful bootable backup feature and continuous backup capabilities, the software provides good value for users looking for a reliable backup and recovery solution.

Top AppleJack Cons
  • Project abandoned. AppleJack is no longer actively maintained, which may lead to compatibility issues with newer macOS versions.
  • Command-line interface. The command-line interface may be challenging for users unfamiliar with command-line utilities or Single User Mode.
Detailed overview

Usability

AppleJack is aimed at advanced Mac users who are comfortable using command-line interfaces and Single User Mode. It presents available options in a text-based menu, and users must enter their choice and press Enter to execute the desired action. While the text-based menu is structured well, with all options clearly described, it’s still significantly more intimidating than disk repair tools with a graphical UI.

Recovery/repair performance

AppleJack offers several disk repair and maintenance features, such as repairing hard drives, repairing permissions, removing corrupted cache files, and validating system preference files. As we’ve already mentioned, it operates in Single User Mode, which allows it to work even when a Mac can't boot into macOS. The software definitely does what it promises to do, and it’s most useful when you can’t load the macOS GUI and need to troubleshoot using the Terminal app. 

Value

As a freeware tool, AppleJack provides value for advanced Mac users who are comfortable with command-line utilities and seek a no-cost solution for disk repair and maintenance tasks. Unfortunately, its lack of active maintenance and potential compatibility issues with newer macOS versions make it less useful than it would be otherwise.

Top Causes of Mac Hard Drive Damage

Even the most reliable hard drive in the world can fail or become corrupted for a number of reasons:

Software bugs

When privileged software applications misbehave, they can cause filesystem corruption or make it impossible to boot into the operating system. That’s why you should never give admin permissions to applications you don’t fully trust.

Human error

It’s natural for us to make mistakes, especially when we attempt something for the first time, such as partitioning a hard drive. Unfortunately, human errors can have disastrous consequences and lead to permanent loss of data, so be extra careful and never follow any online instructions without cross-referencing them first.

Hardware failure

Hard drive reliability statistics don’t lie: there isn’t a single manufacturer that produces hard drives with 100 percent reliability. To avoid data loss caused by a sudden hardware failure, use a disk health monitoring tool and replace the hard drive before its condition deteriorates too much.

Firmware issues

There have been several causes of faulty hard drive firmware leading to hard drive damage and data loss in the past. While hard drive manufacturers are usually quick to release an updated version of the firmware, it’s up to end-users to update their hard drives.

External factors

Hard drive damage can also be caused by external factors such as natural disasters, power surges, and various unforeseen mishaps. Having a reliable backup plan in place is the only way how you can always be prepared for the worst.

Uses and Limitations of Hard Disk Repair Software Solutions

Hard disk repair software solutions can be an invaluable tool in your Mac maintenance arsenal, but they’re not a one-size-fits-all solution. Here are some scenarios where they excel and others where they might fall short:

➕ Uses of hard disk repair software:

  • Data recovery: Hard disk repair software can help you recover lost or deleted files from formatted, corrupted, as well as healthy partitions by recognizing the signatures of individual file formats or locating files based on available or reconstructed file system information.
  • Repairing disk errors: Disk repair software can fix file system inconsistencies, directory issues, and other errors that can cause system instability or crashes. By resolving these issues, you can help your Mac run smoothly and prevent data loss.
  • Performance optimization: If your Mac is running slower than usual, disk repair software can help improve its performance by defragmenting the drive (for HDDs), cleaning up unnecessary files, and optimizing the file system.
  • Preventive maintenance: Regularly using disk repair software for S.M.A.R.T. diagnosis can help identify and resolve potential issues before they become serious problems. For example, you can identify an alarmingly large number of bad sectors and replace the drive in a time manner.

➖ Limits of hard disk repair software:

  • Severe data corruption: In cases where the file system is severely corrupted beyond repair, especially due to physical damage, disk repair software may not be able to repair it and recover the data. In such situations, professional data recovery services might be required.
  • Encrypted drives without keys: If a drive is encrypted and the user has lost the encryption key, disk repair software won’t be able to access or repair the drive’s contents. The only solution is to keep looking for the key because even professionals can’t decrypt state-of-the-art encryption.
  • Advanced malware infections: In cases of advanced malware infections that have deeply compromised the system, disk repair software may not be sufficient to remove the threat or repair the damage. This is especially true when it comes to ransomware, which is designed to encrypt the drive.

Did You Know?

Each year, data storage provider Backblaze gathers data about over 100,000 spinning hard drives used in its cloud storage ecosystem, summarizing the gathered data in comprehensive reports published on its website. On average, approximately 2 percent of hard drives used by Backblaze fail each year, which means that 2 out of every 100 hard drives go to Silicon Heaven.

Conclusion

After testing countless Mac disk repair software applications, we were able to narrow them down to just 10. Disk Drill for Mac earned the top spot thanks to its ease of use, excellent data recovery performance, and useful disk repair tools. Overall, Mac users can choose from a wide variety of disk repair tools, many of which are free or offer a trial version.

You can run whole disk repair on a Mac by launching the diskutil application in Terminal:

  1. Launch Terminal from the Utilities folder.
  2. Type or paste in the following command: diskutil list
  3. Remember the name of your disk.
  4. Issue the following command to repair it: diskutil repairvolume [disk name]

Disk Utility can fail for many different reasons. The disk may have suffered mechanical damage, the file system may be corrupted, or there may be malware present on the system that’s blocking Disk Utility and preventing it from finishing the repair process.
