Method 1: Use ‘Disk Utility’

You can run the diskutil command through Terminal to verify and repair the corrupt drive or volume.

If your Mac partition is corrupt, the foremost thing you need to do is verify it. To do this, proceed with the below-mentioned steps:

  • Further, enter the command: diskutil verify Volume [drive name] in the same Terminal window.

Note: Make sure to replace [drive name] with the identifier that you noted above.

  • Wait until the verification process completes and carefully read the last text in the Terminal window.
  • If it displays “The volume /dev/rdisk3s1 appears to be OK,” it signifies that the hard drive, partition, or volume that you want to verify is not corrupted. However, if the text states “The volume Macintosh HD was found corrupt and needs to be repaired,” then proceed to the further steps.
