the way i fixed this is to edit my Drive Utilization sub reports SQL Where statement to the following. you can add additional filters to the statement inside the brackets. i did it in my sub report so that other reports would not show the recovery drives as well.
DriveIsInternal = 1 and DriveVolumeName not in ('hp_recovery' , 'hp_tools' , 'lenovo_recovery' , 'system reserved' , 'os_tools' , 'recovery image' , 'recovery')
