Storage Pool & Virtual Disk problems

I'm having a huge problem with storage on one of our servers.  We have several Windows servers... all Server 2012.  We use DFS-R for our main data shares.  One of our servers, however, developed a storage problem, so it's no longer a part of DFS-R.  For the life of me, however, I cannot figure out hot to fix it.  

The virtual disk has become corrupted somehow.  Because there is no key data stored on here, I want to remove the virtual disks and storage pool, rebuild them and start again.  But, I just cant make that happen.  I've tried the following Power Shell commands with no success:

• Disconnect-VirtualDisk -FriendlyName "DFS 1" - Returns with Access Denied StorageWMI: 40001
• Remove-Storagepool -FriendlyName "ABC DFS 1" - Returns The storage pool could not complete the operation because its health or operational status does not permit it. StorageWMI 48006
• Get-StoragePool "ABC DFS 1"| Set-StoragePool -IsReadOnly $false - Returns Access Denied StorageWMI 40001

And a few other commands, with on success.

When I run Get-PhysicalDisk, there's a strange thing, too: 

FriendlyName        CanPool             OperationalStatus   HealthStatus        Usage                             Size
------------        -------             -----------------   ------------        -----                             ----
PhysicalDisk0       False               OK                  Healthy             Auto-Select                  465.76 GB
PhysicalDisk1       True                OK                  Healthy             Auto-Select                    1.82 TB
                    False               Lost Communication  Warning             Auto-Select                    1.82 TB
PhysicalDisk2       False               Starting            Unknown             Auto-Select                    1.82 TB
PhysicalDisk3       False               Starting            Unknown             Auto-Select                    1.82 TB
PhysicalDisk4       False               Starting            Unknown             Auto-Select                    1.82 TB

In the 3rd line, there's a "mystery" physical disk (that's also missing a friendly name).  The reason that this is an issue is that there's only four 2TB disks in this machine.  So, the machine has "Lost Communication" with a device that doesn't exist.  And, no, we've not pulled, replaced or added any new hardware.

I've read every article here on TechNet that deals with Windows Server 2012 Storage Pools, and can't get anything to work.  Can anyone tell me how to fix this?  I really don't want to reimage this machine... it also hosts the print queues for many of our shared printers and that would just make mlife a little too difficult now ;-)

Thanks!
