When checking the event viewer, Windows will log the following error:
Volume \?\Volume{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} {\Device\0000003f} needs to be taken offline for a short period to perform a Spot Fix. Please run "CHKDSK /SPOTFIX" locally via the command line, or run "REPAIR-VOLUME " locally or remotely via PowerShell
This error shows up for several different GUIDs.
Using mountvol to check all the volumes on my PC to which Windows has given a GUID gives several results, but the GUID that the event viewer reports doesn't show up. Neither of them show up in that list. They also don't show up at HKLM\SYSTEM\MountedDevices in the registry keys.
To what volume might Windows be referring, what are the possible problems this might cause, and how can I suppress this problem (since running diskchecks is impossible on unexisting volumes)?
