The DiskWizard Extended Capacity Disk tool displays the report below:

A simple click of the 'extend capacity' text allowed PCSTATS to configure a new partition which will draw from the remaining 0.8TB portion of the 3TB Barracuda XT hard drive.

The result is shown below. The new 'virtualized' disk and partition are nothing more than the 0.8TB section of the Barracuda XT.

Using DiskWizard PCSTATS can also remove the extended capacity and resize the partitions as required.

That's all there is too it. Simple indeed. Benchmarks are next.
