I recently purchased a My Book Essential 3TB drive. I Deleted the total volume. This created 2 separate areas on unallocated space. 1 wi/2+TB of unallocated space. The other with 746.5 GB of unallocated space. I was able to create 2 simple volumes in the 2+TB area. However, cannot allocate/create partition in the 746.5 area. Just allows PROPERTIIES. Using Win7’S 64-Bit to create partitions. How can I created a 3 partition out of the 746.5 GB?
It’s a format issue on drives above 3T read through this post http://community.wdc.com/t5/My-Book-for-PC/3TB-Essential-Win-7-32-bit-System-Backup-Failing/m-p/126100/highlight/false#M4597
That did the trick. Thanks for the help
