Server 2012 - Shadow copies on volume D won't enable or reconfigure. Error

I have a server 2012 machine that is having VSS isssues.

I have shadow copies successfully enabled on volumes C:, and E:, but D: will not allow me to enable it, or reconfigure it.

Event log is logging EventID 12290 over a dozen times a minute:
Volume Shadow Copy Service warning: GetDiskFreeSpaceEx() for \\?\Volume{f0a99496-86a6-11e2-93e7-806e6f6e6963}\ failed with 0x00000005.  hr = 0x00000000, The operation completed successfully.
Context:
   Volume Name: D:\


Shadow Copies is currently disabled on Volume D.

When I try to enable it, I get "Failed to create a shadow copy of volume D:\ Error 0x8004231f:Insufficient storage available to create either the shadow copy storage file or other shadow copy data."

When I click settings on it, the storage area dropdown only contains volume C, volume E, and the GUID of the recovery partition.  Volume D is missing as an option.

I set it to volume E, and set the use limit to 320MB and click OK and I get: "The specified storage area association was not found. The settings dialog is closing."


vssadmin list shadowstorage results in:

Everything looks ok... but when I try:
vssadmin resize shadowstorage /For=D: /On=D: /MaxSize=10% I get "Error: The specified volume shadow copy storage association is not found."



I'm completely stuck. I can't enable it or reconfigure it volume D.
