The surface scan delay is the time interval before surface scan analysis activates. This time does not begin counting until there are no commands being sent to the controller. Surface scan analysis is a background process that scans hard drives for bad sectors in fault tolerant logical drives. In RAID 5 or RAID ADG configurations, surface scan also verifies the consistency of parity data. This process assures that you can recover all data successfully if a drive failure occurs in the future. The possible value is 1-30 seconds.
