发明名称 Method and system for predicting disk drive failures
摘要 A method and system within a data processing system for predicting failure of a hard disk drive having a fluid bearing during runtime operation of said hard disk drive, wherein said fluid bearing has an established signature dynamic fluid response. First, a runtime vibration level of the fluid bearing is measured. This runtime vibration level is then translated into a runtime dynamic fluid response which provides an indication of the operating condition of the fluid bearing. The runtime dynamic fluid response is compared with the baseline dynamic fluid response in real-time during operation of the hard disk drive. Finally, in response to a predetermined departure of the runtime dynamic fluid response from the baseline dynamic fluid response, a protective response is initiated, such that data loss within the data storage system due to fluid bearing failure is prevented.
