# Running Patrol Read

A patrol read periodically verifies all sectors of the drives connected to a controller, including the system reserved area in the RAID configured drives. You can run a patrol read for all RAID levels and for all hot spare drives. A patrol read is initiated only when the controller is idle for a defined period and has no other background activities. You can set the patrol read properties and start the Patrol Read operation, or you can start the patrol read without changing the properties.
