Error when Mounting a backup volume

When I try to mount a volume in Norton Ghost 15, I receive the following error: E98F002C. The volume mounts (apparently) successfully, but it does not automatically open. 

 

When I try to dis-mount the volume, I receive the following error message: "Cannot retrieve drive information" and the drive does not dismount. 

 

This appears to have started after moving the backup files from one drive to another. 

 

Any suggestions as to how to correct this?
