Resolutions

If that does not work, check your hardware for any failures.

1. Use Disk Management to rescan the disks and then reactivate any failed disks or volumes.

2. Resynchronize or regenerate the volume as necessary if the disk was a member of a mirrored or RAID-5 volume.

3. Run chkdsk on any reactivated volumes.
