A method is disclosed for ordering error recovery steps of an error recovery procedure executed by a disk drive, wherein each error recovery step having an execution time. The disk drive comprises a disk having a plurality of tracks, wherein each track comprises a plurality of data sectors. A plurality of step success counters are initialized, wherein each counter corresponds to one of the error recovery steps. A plurality of the error recovery steps are executed, wherein if an error recovery step successfully recovers one of the data sectors the corresponding step success counter is incremented. A step priority value is computed for each error recovery step in response to the step success counter and execution time for each step. The error recovery steps are then ordered in response to the step priority values.
A disk drive comprising:
A method of ordering a plurality of error recovery steps of an error recovery procedure executed by a disk drive, wherein each error recovery step having an execution time, the disk drive comprising a disk and a head actuated over the disk, wherein the disk comprises a plurality of tracks and each track comprises a plurality of data sectors, the method comprising the steps of:
