Once upon a time interested in this question. On the old Sigaty could set utilico (even Dozovuju) change the performance/noise, but then her site was removed and a new series of hardy it no longer worked. As it turned out, the patent for Acoustic Management was IBM, now accordingly, Hitachi. I assume that the firmware of hard drives still somewhere remained able to tweak, but in the formality and accordingly the correctness of the method guarantees no one will not give.

PS: In the faq on the website of Sygate to the question "is it possible to reduce noise at the expense of performance?" was given a terrific response — "we produce only high-performance hard!"
