This post tells how to reformat WD hard drive, like WD Elements hard drive for Mac and PC.
“I have a 1TB WD Elements Portable USB 3.0 hard drive, formatted with NTFS and used with PC running Windows 10. Now, I need to use it with my Mac to save some files. I wonder whether I can just use it with Mac directly or need to reformat it for Mac? If the WD Elements drive needs reformating for Mac? If it is necessary to reformat the hard drive, what kind of file system should I reformat it as? Can I format it for Mac on PC?
If you connect your WD hard drive without reformatting, you’ll be unable to copy files to the disk as Mac read only supports NTFS file system. In such a case, it’s necessary to reformat WD hard drive to make it compatible with Mac operating system.
Mac OS X is able to support HFS+, FAT32 and exFAT drives and Windows can support NTFS, FAT32 and exFAT. Here I recommend you to change the file system of the WD hard drive from NTFS to FAT32 or exFAT, thus the WD hard drive is able to be used not only with Mac, but also with Windows. And if there is a large file beyond 4GB in file size, exFAT file system will be the better choice as FAT32 is with file size limit.
After realizing that you can reformat WD hard drive to FAT32 or exFAT to make it compatible with Mac OS X and still can be used under Windows, it is time to check out how to reformat WD hard drive for Mac and PC in Windows successfully. Here are two ways offered and you can choose based on your own situation.
Warning: Format will erase all data on the partition of WD hard drive; therefore you need to back up your important data at first.
The first tool that occurs to your mind to format WD hard drive might be File Explorer. However, in File Explorer, if you right-click partition on the WD hard drive and choose “Format”, you’ll find that there is no exFAT option. At this time, you can format WD hard drive to exFAT via Diskpart. The steps are listed as follows:
1. Press “Windows + R” simultaneously, input “diskpart” in the pop-up box, and hit “Enter” to run Diskpart utility as administrator.
2. In Diskpart window, input the following commands and every command shall come with pressing Enter key.
▪ list disk ▪ select disk n, where “n” is the number of the WD hard drive ▪ list partition ▪ select partition m, where “m” is the WD hard drive partition number ▪ format fs=exfat
Note: If you want to format the WD drive to FAT32, replace "format fs=exfat" with "format fs=fat32".
After the partition on the WD hard drive has been formatted successfully, you can type “exit” to close up the window.
It seems rather simple to employ Diskpart to reformat WD hard drive to exFAT or FAT 32 to make it compatible with Mac and PC, but you are likely to make mistakes even format a wrong partition when using Diskpart if you are unfamiliar with computer knowledge. And When the partition on the WD hard drive is larger than 32GB, you can’t reformat it with FAT32 file system within Diskpart.
At this point, you can try the comprehensive and powerful GUI format tool – AOMEI Partition Assistant Standard, which can work with Windows 10/8.1/8/7, XP, and Vista. It enables you to format WD hard drive, Seagate hard drive, Samsung hard drive, etc. with exFAT or FAT32, even the partition is beyond 32GB.

Step 1. Run the software. Right-click the partition on the WD hard drive and choose “Format Partition”.

Step 3. Return to the main interface. Check the pending operations and click “Apply” to execute it.
After a while, the WD hard drive will be formatted to exFAT for Mac through AOMEI Partition Assistant. Then the file is able to be copied to it under Mac operating system.
