The following tip is excerpted from my book Training Guide: Installing and Configuring Windows Server 2012 from Microsoft Press:
Do not compact, convert, expand, shrink, or merge a virtual hard disk when any of the following conditions apply:
- The disk is associated with a virtual machine that has snapshots.
- The disk is associated with a virtual machine that has replication enabled.
- The disk is associated with a chain of differencing disks.
If you perform any of these actions under such conditions, data loss or corruption might occur.
The above tip was previously published in an issue of WServerNews, a weekly newsletter from TechGenix that focuses on the administration, management and security of the Windows Server platform in particular and cloud solutions in general.
