When creating a workflow for taking a DeployStudio image of a windows NTFS volume — it is important to uncheck the box for use “mac tools for multicast” which then allows you to check the box for “try to shrink the NTFS volume before taking image”. If you do not shrink the volume the imaging process will fail with an error about not being able to change the partition size.

Watch for this setting since it can revert back to the default “multicast” setting, which does not work, when you upgrade the DeployStudio software
