I hope this question has not been asked previously.... if so I apologise.
I Just recently bought one of these. I tried to partition this using Windows 7 Disk Management. I wanted only two partitons, but somehow windows partitioned the drive into three.
1397.39GB Primary Partition
746.52 GB Unallocated
I can format the 650GB partition one, but could not format the 746.52GB partition. I could not even delete the unallocated it.
Is this a problem with windows disk management not recognising disks greater than 2GB? or do I have to use third party software to partition the disk?
I would appreciate any help,
Thanks in advance.....

I'd just try again, delete everything first and then retry.

Thanks for that, but for some reason I could not delete the unallocated partition using Windows 7 Disk Management (running 64bit). In the end after some searching through the internet, I had to do the hard way, ie using command prompt level and using the command 'diskpart'.
Once I deleted all the partitions, I did as you suggested and tried again. Lo and behold, it now partitioned into two using Windows 7 Disk Management.
Unfortunately, in my frustration I purchased Acronis Disk Director which I really don't need now. But I am sure I will find some use for it.
Thanks again for your help, really appreciated.

I have windows 7 64-bit and the GoFlex 3T USB 3.0 drive. Windows 7 would not allow me to use the Window 7 backup on the out of box configuration of the GoFlex 3.0 Drive. So I decided to drop the partition and reformat it to see if this will fix the issue. When I did delete the volume I found the drive was split into three volumes just like you described. To solve this I right clicked in the area to the left of the volume (in the box labeled disk 1 - which is my GoFlex Drive) and used different menu appeared. Use this menu to extend the volume. Then right click on the volume to create a simple partition.
I am now able to use Window 7 backup to create backups sets and disk images.

What is actually happening is that your drive was re-partitioned under and MBR (Master Boot Record) to which is limited to 2.2TB in size which is why you could not format the third section and why it created a third partition.
The solution is to Right-Click on the drive in the Disk Management program and click "Convert to GPT" and under a GPT partition, the drive can be partitioned into 2 sections of what-ever size you want - as long as your drive is smaller than 16 Zeta-Bytes (I have a feeling that it isn't or won't be for a long time).
