External drives are portable hard drives which can be used for storing data which you want to keep on hand during your travels. Most of the external drives especially the WD ones available in the market are either formatted in NTFS or HFS+ format. The NTFS format is for Windows while HFS+ is for Macs. However, the new Macs are shipped with the latest Mac OS version, macOS High Sierra which supports the Apple File System or APFS. If your WD external drive isn’t in this new format, you won’t be able to use it if your Mac has been updated to macOS High Sierra. In such cases, you need to simply convert your WD external drive to APFS format.
If you want to format your external drive from its existing file format to the new Apple file format, APFS or Apple File System then you should follow these simple steps.
APFS is the short form of Apple File System. It was introduced by Apple in the year 2006 and is now the default file system of the latest Mac operating system, macOS High Sierra. This new file system replaces the previous file system, Mac OS Extended or HFS+, which was used by all the Mac OS versions which came before it. It offers a number of advantages over its predecessors and is automatically applied to your hard drive upon the installation of macOS High Sierra. APFS has been optimized for SSDs and flash drives but can be used for external and hybrid drives as well. However, it is best suited for flash and solid state drives.
One thing to keep in mind about APFS is that it only works on macOS High Sierra. So, if you don’t have this Mac OS installed on your Mac, you won’t be able to open any drives using the APFS format.
APFS offers a ton of benefits which you don’t find in HFS+. Moreover, it is also the recommended file system for SSDs and flash drives. The following are some of the advantages that you can avail by converting to APFS.
If you have bought a new WD external drive which isn’t formatted in the APFS format then you would have difficulty in opening it on a Mac running macOS High Sierra. Moreover, you won’t be able to enjoy the numerous benefits that this new file format has to offer you. In order to make sure that your WD external drive takes advantage of the APFS format, you need to convert it from HFS+ to APFS. You need to follow a simple set of procedures to ensure that your WD external drive is converted to the APFS format. These steps are easier to follow and the whole process wouldn’t take much time to complete.
