Abstract
In a first aspect, a method of operating a disk drive includes detecting a trigger event during non-idle operation of the disk drive, and responding to the detected trigger event by performing a predictive failure analysis with respect to the disk drive. According to a second aspect, a method of operating a disk drive includes performing a predictive failure analysis with respect to the disk drive at a regular time interval, detecting a trigger event during non-idle operation of the disk drive, and responding to the detected trigger event by reducing the regular time interval at which the predictive failure analysis is performed. Numerous other aspects are provided.
