If you are using macOS Big Sur, Catalina, or Mojave, then most likely, your internal storage drive is partitioned in APFS format. In case your Mac is running on macOS Sierra or OS X Lion, the internal drive partition may be in the HFS+ format. Many users, these days, are upgrading their macOS and moving to APFS to be on par with the current technology. 

If your APFS or HFS partition is not functioning properly due to aging or usage, repair the partition immediately to avoid data loss. The next section describes how to fix an APFS or HFS+ partition. 

1. Repair Damaged APFS or HFS Partition by Using Disk Utility

You must be using Disk Utility in your system to perform disk management tasks. You can also use it to repair your logically damaged APFS or HFS partition.

Step 1) Press Command + Space Bar to launch Spotlight, and then type ‘disk utility’ and press Return. The Disk Utility window will open. Or else, navigate to Finder > Applications > Utilities > Disk Utility. Double-click the Disk Utility icon to launch it on your Mac.

Step 2) Select an APFS or HFS partition from the left pane of the Disk Utility window. From the top pane, click the First Aid tab, then click Run. Disk Utility will analyze the partition and repair any logical errors.
