How to run chkdsk on a volume shadow copy

I'm getting a message in event viewer that says I need to run chkdsk on volume \Device\HarddiskVolumeShadowCopy18 but cannot work out how to access the shadow copy in order to do that.  Can anyone advise me how to do that?

In case it helps here is the output from a vssadmin list shadowstorage command:

I am using Windows 7 Home Premium.
