WD My Book 4 Tb (WDBACW0040HBK-NESN) and Windows 8 Pro

WD support is now communicating with me. I managed to get the larger of the partitions to work now. But the smaller 1677.99 GB partition cannot be initialized. Perhaps this is the backup software incipient on the drive? I am attempting to wipe the smaller partition to see if I can initialize and then have it accessible.
