Hi @leonardtangty,

Please refer to the article How to Partition and Format a Drive on Windows or macOS:

For more information, please contact the WD Technical Support team for best assistance and troubleshooting:

Well, most external hard drives are designed to work for Windows computers. Windows was mainly optimized for NTFS (New Technology file system) format, on the other hand, APFS was created for the Mac OS. NTFS is not compatible with Mac and similarly APFS does not get along with Windows. So if you’re trying to connect an external hard drive to a Mac, you might have to format the drive before you can use it.

Further, I suggest you to check the below link that explains all the methods to format your external drive for mac without any data loss:

Hope it helps!
