Step 1. Open Disk Utility from "Go" > "Utilities"

Step 2. Select the corrupted drive in the sidebar (choosing the parent device if multiple volumes exist), and click First Aid.

Step 2. Open Terminal from the Utilities menu

Step 3. Identify your disk using diskutil list

Step 4. Run diskutil apfs repair /dev/diskXsY

Disk Utility Found Corrupt Disk FAQs

If you still have some questions about MacBook data recovery, check the quick answers below to help yourself out:

1. Will Disk Utility's repair delete my files?

First Aid attempts non-destructive repairs, but severe corruption can sometimes lead to data loss during repair attempts - another reason to recover files first. The repair process prioritizes filesystem integrity over preserving every file when forced to make a choice.

2. Why does the corruption keep returning?

Recurring corruption often suggests deeper issues, such as a failing drive, problematic cables or enclosures for external devices, or RAM issues causing write corruption. A consistently corrupt Time Machine backup drive may indicate a problematic USB controller.

3. Can I prevent this error in the future?

Regular maintenance is essential: eject external drives properly, use surge protectors, replace aging drives proactively, and consider RAID mirroring for critical data. For mission-critical systems, enterprise-grade SSDs with power-loss protection offer greater resilience.
