Does anybody know what this Event error means?
Detected a previous crash while re-activating VDIFF on \Device\HarddiskVolumeShadowCopy409. VDIFF is terminated.  This happens on a windows 2003 server SP2 with SQL server 2005 running. This event will follow right afterwards.. Snapshot interface initialized for volume on \Device\HarddiskVolumeShadowCopy410.

I found out that Ultrabak Gold tried to freeze the drive to do a image backup and in doing so generated this error because the database was still in use. Im going to continue this investagation with UBG.
