Acronis VSS Doctor error - "Disk I/O Load" ---> "invalid query"

Thread needs solution

Am receiving an error when running VSS Doctor. Details in VSS show:

"Disk I/O Load

Status: Error
Description: An error occurred when performing a check

Error occurred:
System.Management.ManagementException: Invalid query
   at System.Management.ManagementException.ThrowWithExtendedInfo(ManagementStatus errorCode)
   at System.Management.ManagementObjectCollection.ManagementObjectEnumerator.MoveNext()
   at Acronis.Utilities.VSSDoctor.Collectors.DiskIOLoadCollector.Collect()
   at Acronis.Utilities.VSSDoctor.Launching.Launcher.CollectData(Func`1 cancellationChecker)".

 

Any suggestions as to cause?

Gary,

Disk I/O errors are generally related to bad block(s) on disk.  I would recommend running chkdsk to fix such errors.

If your disk is an HDD then run chkdsk {DriveLetter} /r on all disk partitions.  If your disk is an SSD then use the /f option.

If the disk in question is your Windows system disk and has partitions without drive letters you can use the VSS Doctor tool to temporarily assign a drive letter to such partitions to run chkdsk against them.

After you run chkdsk have a look at Windows Event Viewer > Windows Logs > Application then from the right pane, scroll down and double-click to open the Wininit source.  

In the General tab look for the results of the chkdsk scan and locate the bad sectors line.  A 0 KB entry means your disk is healthy.  Any other number means your disk is headed for failure and is a candidate for replacement.
