Storage spaces can only use whole drives

Question

One of the features that I was really interested in with WS2012E is storage spaces as it replaces the old driver extender of WHS v1. Having now installed WS2012E onto my WHS2011 box I am bit staggered to find that it can only use whole drives. My box came
with 2 * 2Tb drives, the first partitioned as boot, then a 60G of OS followed by the rest allocated as storage. I have successfully created a Storage space pool of the second drive but cannot find any way to add the remaining storage from the large partition
on the other drive into the pool. As the UI just shows me drives rather than partitions, I am bit challenged. I thought that storage spaces was meant to be flexible about adding drives just like the old drive extender. Even add on technolgies like DriveBender
for WHS2011 allows for a storage space to be made up from this type of set up. So we seem to be going backwards.
Plus when creating the drive pool it defaulted on a 2Tb drive to a 2Gb size! How useful is that? As soon as I started copying data to the drive it ran out of space. I then had to go in and expand it.

I note that you did this with Windows Server 2012 Essentials.  I cannot seem to do this with Windows 2012 Standard.  I have two 500 GB disks and 40GB of the first disk, PhysicalDisk0 is partitioned for the OS.  Nothing I do makes PhysicalDisk0
show up in the Storage Pool area of Server Manager - all I can see is PhysicalDisk1.  (Refer to 'Physical Disks' in the bottom right corner of the previous poster's first screen shot above.  I can only see 'PhysicalDisk1', not 'PhysicalDisk0'.)  If
I click 'Disks' just under 'Volumes' in the same screenshot above, I can see PhysicalDisk0, and it shows 466 GB capacity, 423 GB unallocated.  PhysicalDisk1 shows 466 GB capacity, 466 GB unallocated.  My intent was to mirror the remaining 423 GB
on PhysicalDisk0 with 423 GB on PhysicalDisk1.  I would then allocate the leftover 43 GB on PhysicalDisk1 as a 'scratch' disk.  I have tried leaving everything unallocated and have tried all variations of creating volumes and virtual disks, but nothing
I do makes a difference.  I found other threads related to this issue which indicated there was a flaw in the 2012 GUI and that this process could be done via Powershell.  However, there seems to be a mix of Windows 8 and Windows 2012 in these threads
and, apparently the Powershell commands I've found apply to 8 and not 2012, as I get invalid command errors when I try to use them.
Can anybody tell me how to mirror the unallocated portion of the primary disk PhysicalDisk0 (which has a partition for the OS) with a same-sized portion of PhysicalDisk1 with Windows Server 2012?  Thanks!
