Creating partitions on Mac is essential for organizing data and ensuring seamless device performance. However, sometimes these partitions get corrupted or become inaccessible. In such cases, you may encounter data loss issues on your Mac partition. If you find any data deleted from your device partition, don’t panic! This guide will walk you through various effective methods to help you learn how to recover data from corrupted Mac partitions.
What Causes Mac Partition Corruption?
Before you proceed with data recovery on Mac, understanding the causes of corruption is essential. Common reasons include:
- File System Errors: There may be problems in HFS+, APFS, or other macOS file systems, which can corrupt partitions.
- Unexpected Shutdowns: Sudden power outages or abrupt system shutdowns can also cause partition errors.
- Hardware Failures: Aging or damaged hard drives (which generally occur due to continuous use) often result in partition corruption.
- Software Issues: Malware, incompatible software, or bugs can corrupt file systems and cause data loss.
- Improper Partition Management: Errors during resizing, formatting, or partitioning the Mac partition sometimes lead to data corruption or loss.
Signs of Corrupted Mac Partition
Now that you are familiar with the reasons why Mac partitions usually get corrupted, it’s time to check what happens when such corruption occurs:
- Files or folders became inaccessible.
- You receive error messages such as “The disk you inserted is not readable by this computer.”
- The partition fails to mount in Disk Utility.
- macOS takes longer than usual to access files.
When you encounter any of the above issues, it’s important to take immediate action to prevent further damage.
How do I Recover Data from Corrupted Mac Partitions
It is important to act immediately when you find your Mac partition corrupted or data loss issues on it. You should also avoid saving new files on the corrupted partition. Continued use can overwrite data, making recovery harder or impossible.
Now, let’s discuss common methods for data recovery on Mac to restore your lost files from a corrupted Mac partition:
Method 01: Use Disk Utility to Diagnose the Partition
macOS provides a built-in Disk Utility tool, which you can use to diagnose and repair minor disk issues. Here’s how:
- Launch Disk Utility from the Application > Utilities folder.
- Select the corrupted partition from the left navigation pane.
- Now, click First Aid and then hit the Run button to start the repair process.
Disk Utility will try to fix errors in the file system. If it’s successful, you can access the data again. However, if repairs fail, proceed to advanced options from data recovery on Mac.
Method 02: Recover Lost Data Using Time Machine Backups
If you’ve enabled the Time Machine backup utility on your Mac, you can use it to restore data when sudden data loss occurs. Follow the below steps to recover data from Time Machine:
- Firstly, connect the Time Machine backup drive to your Mac.
- Open the folder where your deleted file was earlier stored.
- Click on the Time Machine icon from the menu bar and browse through available backups.
- Select the desired backup which you want to restore and click Restore.
Time Machine works only for the recently created backups. If the required backup of your deleted file is not present, you’ll need to use a professional Mac data recovery software.
Method 03: Use Free Mac Data Recovery Software
When built-in options fail, specialized free Mac data recovery software such as Stellar Data Recovery Free for Mac allows you to recover lost or deleted data without any cost. You can use this professional data recovery software to recover files deleted due to accidental deletion, formatting, virus attacks, or any other reason.

Method 04: Seek Professional Data Recovery Services
If all the above methods fail to recover data from corrupted Mac partitions, it’s time to consider professional data recovery services. These services often involve cleanroom technology to handle physically damaged drives.
When to consider this option:
- The partition is physically damaged.
- The drive produces clicking noises.
