Volsnap Event ID 16

Hi,

I have a win 7 x64 ultimate machine with a dual boot with win 8 on a D: drive.

Now I get the following error:

Event ID:      16
Task Category: None
Level:         Error
Keywords:      Classic
User:          N/A

The shadow copies of volume D: were aborted because volume D:, which contains shadow copy storage for this shadow copy, was force dismounted.
