Abstract:
1. A system, comprising: at least one processing device; an information handling system chassis including at least one of an enclosure, a frame, or a combination thereof; at least one magnetic disk drive mechanically coupled to the chassis, the disk drive being configured to generate position error signals (PES) data, and to provide the PES data to the at least one processing device; one or more vibration sensor components configured to sense at least one of mechanical or acoustic vibrations simultaneously with the generation of the PES data by the disk drive, and to provide sensed vibration data representative of the sensed mechanical or acoustic vibrations to the at least one processing device; and at least one vibration source configured to operate at different operational levels that produce different corresponding frequencies of vibration; where the at least one processing device is configured to at least one of:
