The volume snapshot driver encountered an error while performing processing for dismount.

Error: %3
Error Details: %2

Volume GUID: %1

Guidance:
When a volume is dismounted, the volume snapshot driver closes any handles it may have open on the dismounting volume, such as handles to diff areas.  All auto-release snapshots that have diff areas on the dismounting volume are deleted at this time. The volume snapshot driver may also perform some work to detect whether any future direct writes to the volume are to diff area space for persistent snapshots.  If such writes occur this detection work allows the volume snapshot driver to destroy the snapshots, since the direct volume writes may corrupt them.

A failure during this process results in loss of all snapshots whose diff area files are located on the volume, unless those snapshots are of volumes that are in snapshot protection mode.
