How to fix "Finder cannot find APFS partition"?

Posted by Katrina to Mac Data Recovery on January 9th, 2018

I have a 2 TB Toshiba external hard drive, one of its partitions was formatted to the newly released APFS. But this morning, when I inserted the external hard drive on Mac, I didn't find the APFS partition in the Finder. Then I went to Disk Utility, it was displayed as not mounted. I have to access the important files stored in the APFS partition. Can anyone tell me how fix Finder cannot find APFS partition? Any help would be appreciated!

Normally, a mounted APFS partition will be seen on the desktop or in the Finder in the left-hand column under Devices. However, it fails to mount at times when we desperately need to access some data stored on it. Such a situation annoys a great amount of macOS users.

Two cases of "Finder cannot find APFS partition"

1. The APFS partition cannot be mounted. When our APFS partition is unmountable, we cannot find it in Finder but we can see it unmountable in Disk Utility.

2. The APFS partition is lost. Once our APFS partition is lost, Apple operating system cannot recognize the APFS partition anymore that we cannot see it in Finder or Disk Utility.

How to fix "Finder cannot find APFS partition"?

Based on these two cases, we offer you two solutions to fix "APFS partition not showing up in Finder" without data loss.

Solution 1: Mount APFS partition with Disk Utility

Open Applications > Disk Utility and look in the list on the left to see if the APFS partition appears there.

1. The APFS partition shows up in Disk Utility

a. Right-click on the APFS partition and select Mount.

b. If the Mount option is greyed out, the APFS partition is unable to access. The only choice is First Aid. Select the APFS partition and click the "First Aid" tab and select Run. First Aid will check the disk errors and then repair the disk if necessary.

2. The APFS partition does not show up in Disk Utility

If your APFS partition doesn't appear in Disk Utility, it refers to partition loss. The APFS partition loss is such a serious problem that First Aid cannot fix. The only way is to find professional lost partition data recovery software to find lost data back.
