How do I partition a MyBook 16TB WDBBGB01160HBK-NB

Would like to partition this drive into 2 equal sized partitions. When I select the drive in Windows Disk Management, the Partition Drive option is not active.
Thanks in advance.


For deleting all the partitions and creating one, please follow the below mention link :

Right-click the external drive or USB you intend to format and choose “Format”. Set the Partition label, File system (NTFS/FAT32/EXT2/EXT3/EXT4/exFAT), and Cluster size, then click “OK”. Click “OK” to continue. Click the “Execute Operation” button and click “Apply” to format the hard drive partition.
