I used to write the firmware that runs the tracking systems for disk drives (specifically, some of my stuff was in the Quantum Atlas III, IV, 10K, and 10K II). This does not surprise me at all. Cabinet vibrations were always a HUGE component of track mis-registration (i.e., the heads going off the tracks). It used to really annoy us when the cabinet and workstation manufacturers would stick our drives in flimsy, crappy components and wonder why the performance would suffer.
Enterprise drive makers like Seagate and WD are now claiming to have features which limit the damage caused by cabinet vibrations. I was intrigued to note that these differences are done only with firmware.
Any idea whats happening behind the scenes? I assume Seagate measured the common vibration frequencies and conteract them with head movements?
