Validation of diff area files encountered an error.

Error: %2

Volume GUID: %1

Guidance:
When a volume is mounted, the volume snapshot driver reads and validates all the diff area files located on the volume.  These diff area files may be for persistent snapshots of the volume being mounted, or for persistent snapshots of other volumes.  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.
