How to convert HFS+ to APFS without losing data?

Posted by Juno to Mac Data Recovery on August 17th, 2017

As a new file system developed by Apple Inc, APFS has a lot of breakthroughs compared with previous file systems (HFS, HFS+, etc.). Some key features of APFS are really attractive, like copy-on-write metadata, automatically cloning for files and directories, snapshots, space sharing among partitions, strong encryption.

In short, APFS has improved a lot on management of drive space & file security and becomes the best choice for Mac users. However, many of us are not really using APFS. Why that happens? Not because we don't care about the security of our files, but just because only on macOS 10.13 the default file system is APFS and macOS 10.13 is not the one we are using. On most other Mac Operating System, the default file system is HFS or HFS+. So just find the method to convert HFS+ to APFS, and then we can benefit from APFS - the amazing new technology!

How to convert HFS+ to APFS without losing data?

To convert a hard drive or external hard drive from HFS+ to APFS, we even needn't download any software or back up files in advance. Just finish the 3 steps below:

1. Open Disk Utility and find the drive that we want to convert to APFS.

2. Right-click the drive and choose "Convert to APFS".

3. Wait until the conversion process finishes.

It's so easy that we all can do it without any previous skills. At most of the time, this method works and we can use APFS henceforward. But it should be noted that the real conversion operation varies from situation to situation and this method may fail to work sometimes.

Generally speaking, the conversion failure is caused by unexpected power off during the conversion process, bug of the Disk Utility, file system error and bad sectors on the drive. Although that happens only in rare cases, it's still helpful to know how to avoid data loss if we fail to convert HFS+ to APFS with Disk Utility.
