Following this guide, you can fix disk repair problems, keep your data safe, and keep your Mac running smoothly. No matter your experience with computers, this guide will teach you how to fix Disk Utility errors and keep them from happening again.

Understanding Disk Utility and Its Limitations

Disk Utility is a built-in app in macOS that lets you control and fix disk drives. It can format, split, and fix small disk mistakes with "First Aid." Notwithstanding what it can do, Disk Utility has its limits and might not be able to resolve all disk problems for the following reasons:

• Severe Disk Corruption: Disk Utility may be unable to fix extensive file system corruption.
• Physical Disk Damage: Software can't fix problems with hardware, such as bad sectors or disks that won't work.
• Unsupported File System: Disk Utility might not fully handle some file systems, which could mean that repairs don't work.
• Permissions Issues: Disk Utility needs to be given the right access to fix things. Not having enough rights can slow down the process.
• Software Conflicts: Sometimes, third-party software can get in the way of Disk Utility's fixes.

Symptoms of Disk Utility Failure to Repair a Disk on Mac

If Disk Utility fails to fix a disk, you might see several things, such as:

• Error Messages: "Disk Utility cannot repair this disk" or "The disk cannot be repaired."
• Unresponsive Disk: The disk might stop being able to be mounted or accessed.
• Data Loss: Files and folders can disappear or get damaged.
• Slow Performance: The system may slow down or freeze up.

If Disk Utility cannot repair the disk on your Mac, you'd better use a Mac data recovery application to help you recover all data from the disk and save the recovered data to another drive.

Step 1. Download and install Donemax Data Recovery for Mac on your Mac, then run it from Launchpad.

Step 2. Open Donemax Data Recovery for Mac, select the damaged disk to start data recovery.

Step 3. Click on Scan button to deeply scan the damaged disk and find all recoverable files including existing files, deleted/formatted/lost files, etc.

Step 4. Once the scan is completed, you can preview all recoverable files. Then select the wanted files, click on Recover button to save them.
