This issue is. I have 2 Seagate 250 gig drive AS 7200.10 and the WD-5000AAKS (i.e. Caviar Green). Looked now tab in the info program HDTune.

There is a parameter that Automatic Acoustic Management at Seagate, he is disabled, the WD has been disabled. Seagate did not hear anything at all, WD - sometimes on the terrible noise.

Judging by the name of the parameter as it is linked to the noise. So, may be to disable it from the WD, if not rustled it? Can it be? And if possible, how it is done in windsurfing?
