Seems like it would have to either stop the drive, maybe triggering shock protection, or make it read incorrect data, which could be possible if the read head's correction mechanism was resonating. If its delay was half the sound's frequency, it would try to correct in the same direction as its being pushed by the sound, causing the feedback loop for resonance.
