Western Digital partitions the 2TB My Passport external hard drives into a single NTFS partition which is optimized for Windows operating systems. This single partition makes reformatting the drive possible through Windows 8's Disk Management utility without needing to create a new volume.
Western Digital external hard drives are useful for storing and backing up files. However, you may have run into a problem trying to use your Western Digital hard drive with multiple operating systems. This is because you must format the drive with a specific file system before using it with a computer, and Windows and Mac computers run on different file systems. The only solution to making your hard drive compatible with a different operating system is to reformat the drive. This, however, erases all of the data on the drive.
