When using a standalone server or virtual machine a copy can be used without issue because there is logic in Windows Server via the Cluster Disk Driver (CDD) that gets notified through Plug-n-Play that a new disk has been added. The CDD then checks the signature of the disk and in the event that signature collision is detected and a new unique value will be created and the disk presented to the standalone server as a new volume. The result is a new disk connected which is based on a snapshot of a volume.
