You may encounter an issue and this error will come up in the logs: 

FileSystemException: Expected a single volume for partition 1 on disk 

If SQL Clone is having issues with creating volumes, try changing the location for clones.

1.  Open C:\ProgramData\Red Gate\SQL Clone Agent\settings.json in an editor
2. Change the null under OverrideCloneLocation to point to the desired location (Note: any backslashes will need to be escaped by entering a double backslash, so it should look something like: "OverrideCloneLocation": "D:\\MyClones")
3. Restart the SqlCloneAgent service
