I am trying to shrink a volume on Windows 7 Professional using Disk Management but get the following error:
Virtual Disk Manager
The service cannot be started, either because it is disabled or because it has no enabled devices associated with it.
The disk I am trying to shrink is not the system disk. However as stated by Disk Management it is: Active, Primary Partition.

I've seen McAfee AV cause a situation where disks cannot be managed. I never figured out why but uninstalling resolved the issue.
I've also seen this issue when the Disk Defragmenter is disabled (for SSD) and turning it on temporarily allowed disk to be managed.
