METHOD AND APPARATUS FOR CONTROLLING WRITE OPERATIONS OF A DATA STORAGE SYSTEM SUBJECTED TO A SHOCK EVENT

摘要

A method and apparatus for controlling write operations for a data storage system during and after a shock event is disclosed. A shock sensor measures the magnitude of a shock event and compares the magnitude of the shock event to at least two predetermined thresholds. Write operations are then inhibited based upon the comparison of the magnitude of the shock event and the at least two predetermined thresholds. When the shock event meets a first upper threshold, the write is inhibited until the write is requalified. The write is executed if the measured shock event does not meet a second lower threshold and the write is paused for a predetermined time period when the measured shock event meets the second lower threshold but does not meet the first upper threshold.
