Find the volume with this GUID: {80cab100-feb3-11e2-b1c9-8<wbr />06e6f6e696<wbr />3}<br />
And run on it CHKDSK /f <br />
Best if you check all the partitions. Looks like VSS cannot take snapshot of one of your partitions or the drive where this partition is located is faulty.

We have some VSS issues on a fully patched SBS 2011, We are running Altaro to backup the VM and have seen this event (Below). Having looked in to it I cannot work out what I should be looking at and fixing. Any hotfixes I find relate to 32bit systems. <br />
<br />
Can someone point me in the right direction.<br />
