I had a drive go out last night and I have been unable to repair the virtual disk on a windows 2012 standard server

Here is the output from the storage pool

PhysicalDisk0 was intended to be the replacement for the retired drive. 

Repair-Virtualdisk completes instantly.

When I try and run

Remove-PhysicalDisk -PhysicalDisks $removehdd -StoragePoolFriendlyName secondstoragepool

I get the following output

PS C:\Windows\system32> Remove-PhysicalDisk -PhysicalDisks $removehdd -StoragePoolFriendlyName secondstoragepool

Confirm
Are you sure you want to perform this action?
Removing a Physical Disk will cause problems with the fault tolerence capabilities of StoragePool "secondstoragepool".
[Y] Yes  [A] Yes to All  [N] No  [L] No to All  [S] Suspend  [?] Help (default is "Y"): Y

Any ideas?
