    摘要: A data storage subsystem in a distributed storage system having a plurality of predictive failure analyzing data storage devices. The subsystem furthermore has a circuit that is responsive to a predicted failure indication by a data storage device in relation to predetermined rules stored in memory for deterministically initiating a preventive recovery either by a data recovery procedure in the data storage device or by a fault tolerance storage arrangement in the subsystem.

    摘要: In a method for predicting failure of a disc drive during operation of the disc drive, a write fault count is maintained that corresponds to write faults encountered during write operations to a disc of the disc drive. Additionally, a frequency domain representation of a position error signal of a head of the disc drive is obtained. Finally, failure of the disc drive is predicted based on the write fault count and the frequency domain representation of the position error signal. Another aspect of the present invention relates to a disc drive that is capable of performing the above-described method.
