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.

摘要： A method of performing predictive failure analysis (PFA) for a disc drive includes maintaining at least two primary error counts during operation of the disc drive. The primary error counts each correspond to disc drive errors associated with different attributes of the disc drive and are potentially indicative of disc drive failure. Imminent disc drive failure is predicted based upon a combination of the primary error counts.
