How to fix 'encryption of APFS volume won't finish on High Sierra'?

Posted by Katrina to Mac Data Recovery on July 24th, 2018

A few weeks ago I told all of my three external hard drives to encrypt. This went well, macOS (10.13.4) converted them to an APFS formatted encrypted volume, except for one drive. This drive doesn't complete it's encryption as it seems. Right-clicking on it shows a greyed-out entry for the "encrypt volume" command. How to fix?

Whatever you update to High Sierra or Mojave‎, your Mac internal hard drive will automatically convert HFS to APFS (encrypted), and you can format or convert external drives to APFS (encrypted) based on your actual needs. But just like the above example, sometimes, encryption of APFS volume won't finish on High Sierra.

Why encryption of APFS volume won't finish on High Sierra?

The main reason why APFS volume won't finish on High Sierra is corrupted file system and damaged partition. In this situation, the operating system is unable to recognize the internal memory and fails to encrypt APFS volume on High Sierra.
