Error message "There is no disk in drive" when running reports

I am sporadically getting an error message when I try to run an individual summary or other reports on some people but not all.

The error message: *There is no disk in the drive. Please insert a disk into drive\Device\Harrdisk3\DR3.*

Resolution: Check if any of your people have links to media items which are on drives that don't exist (CD drives w/o a CD, non-existent flash drives, etc). You also may have broken links that need to be fixed.
