The extensive increase of the rotating speed of HDD (hard disk drive) has improved the performance of HDD. One of drawbacks, however, is that it increase noise level. For the systematic noise control of HDD, it is important to know the way in which each source of HDD contributes to resulting noise. A conventional method for contribution analysis by using statistical information, however, is not proper for HDD. This paper reviews the conventional method, and explains the reason why the method is not proper for HDD, even though it is possible to find the number of independent sources by using statistical information. This paper also shows an experimental result for the identification of the number of independent sources of HDD.
