Most WD Drives come formatted in the NTFS (Windows) or HFS+ (Mac) format. If you own a WD Elements drive in NTFS, it will be only readable but not writable on Mac. How frustrating it is! There is a common need to make WD Elements drives usable on both Windows and Mac so that you can transfer data between the two environments. To achieve this goal, you are supposed to format WD Elements for Mac to FAT32 or exFAT which is compatible on both Windows and Mac.
However, when trying to format WD Elements for Mac, some users encounter such errors:
This error occurs when another program or service is actively using WD Elements, such as a file transfer to or from the drive, or security software scanning the drive for problems. You can fix the error in following ways:
● Close all obviously open programs or files.
● Boot your computer into Safe Boot.
● Temporarily disable any anti-virus and other security software running on
your computer.
● Format the drive using another USB/FireWire/eSATA cable and on another
computer if possible.
If the WD Elements to be formatted contains a GPT partition, Disk Utility will produce the error: “MediaKit reports not enough space on device for requested operation. Operation failed...” To solve this problem, you have to erase the partition first and then format the drive with Disk Utility. You will get a prompt that erasing WD Elements will delete all data stored on it and cannot be undone.
