Assume that on a Windows 8 or Windows Server 2012-based computer, a disk is removed from the computer unexpectedly. In this situation, when you try to back up this computer by using Data Protection Manager (DPM), the backup operation fails together with a Volume Shadow Copy Service (VSS) software provider error message that resembles the following, which indicates that access was denied:
ComputerName : <computername>
SourceName : VSS
EventCode : 12289

Message : Volume Shadow Copy Service error: Unexpected error DeviceIoControl(\\?\Volume{97823f6b-e259-11e2-93fe-6cf049017635} - 00000000000003FC,0x0053c06c,000000BCC1213070,0,000000BCC1214080,4096,[0]). hr = 0x80070005, Access is denied.

Additionally, VSS tracing information is generated that resembles the following:
