RESOLUTION:
Do one or more of the following:
1.Using chkdsk /r, check for errors on the volume where the Diff Area is stored and on the original volume,.
2.Check the system log in Event Viewer for errors associated with the volume where the Diff Area is stored or with the original volume.
3.Check for hardware errors on the disks that contain the volume where the Diff Area is stored and on the original volume.
4.Move the Diff Area to a different, dedicated volume.
5.Move the Diff Area to a larger volume.
6.Allocate more storage space for the Diff Area.
