Easy and quick way to solve the DiskPart error: the Disk Management services could not complete the operation.
When you use the Windows built-in command line tool Diskpart.exe to manage disk or partitions on your computer in Windows 10/8/7 or Windows Server 2016/2012/2008, you might get an error say that the disk management services could not complete the operation. This error message indicates that the Virtual Disk service has been disabled somehow.

2. In the Services window, scroll down to locate the Virtual Disk service.
3. Right click on Virtual Disk Service, and click “Properties”.
4. In the pop out dialog box Virtual Disk Properties, select “Manual” or “Automatic” under Startup type instead of “Disabled”. Then click “OK” to save the change.
5. If the Diskpart has encountered an error like before, locate the Logical Disk Manager Administrative service and manually start the service.
