If you are using macOS Catalina, Mojave or High Sierra then most likely your internal storage drive is an APFS partition. On macOS Sierra and OS X Lion; the internal drive could be an HFS+ partition. However, users are frequently upgrading to macOS Catalina 10.15 and becoming an APFS user.

How to Repair an APFS or HFS+ Partition?

If you are an avid user of macOS, then you must be using the Disk Utility tool actively. Disk Utility plays a crucial role in helping you do repair of APFS partition.

a) Launch Disk Utility on Mac

You can press Command + Space to launch Spotlight and type ‘Disk Utility’ and press Enter to open the application. Else, you can navigate to the Finder — Applications — Utilities — Disk Utility. Double-click the Disk Utility icon to launch on your Mac.

b) Target APFS/HFS Start-up Disk and Repair

After you have successfully launched the Disk Utility application on your macOS, you need to select the Mac partition from the left panel of the utility’s interface. The start-up disk (no matter a hard drive, an SSD or a Fusion Drive) will get listed in that corner. Next, move your mouse cursor to the First Aid tab and leverage this feature to allow the Disk Utility to tour the logical structure of the start-up disk. In the logical tour, the Disk Utility will analyze the partition map, container, and directory structure of the APFS and HFS volume and bring-in the logical errors that it may discover. Nonetheless, the errors will be repaired via the Disk Utility mechanism, and if some error fails to get fixed then the utility will warn you of the next course of action which is:

c) Try Data Recovery when Disk Utility Fails to Repair a Partition

Why data recovery on APFS/HFS comes to the picture here? The answer is simple; if your Mac partition or volume is severely corrupt, then you will not be able to back up its data as you would typically do. Some other critical cases might occur (such as the non-start-up partition gets inaccessible) which requires data recovery immediately. Once all the data is recovered successfully on an external storage drive, then you can bravely proceed to erase the affected ‘Mac start-up disk’ or the ‘volume’ via Disk utility in recovery mode.
