Abstract: Apparatuses and methods are disclosed that relate to movement of actuator arms from a stopped position. In one example, a method may include attempting to unlatch an actuator arm from a stop and measuring an electrical parameter of a driver circuit of the actuator arm. The method may further include detecting an unsafe unlatch event using a controller when the electrical parameter does not exceed a first threshold within a predetermined period of time.
