Many modern hard drives support a function called AAM – Automatic Accustic Management. The feature is currently supported by most hard drives from Samsung, Maxtor and Hitachi. Most hard drives have the feature disabled by default which decreases access time but increases the noise level of the hard drive. If you prefer silence over performance you might want to enable AAM to decrease the noise level of your hard drive and slightly increase the access time.
Silence or Speed up your Hard Drive
Automatic Acoustic Management is a feature of most modern hard drives which reduces the seek noice at the cost of perfomance. Most hard drives have this feature disabled but it is possible to enable it using a tool like silent drive which runs on Windows Xp and 2000 only. Please note that silent drive is only working with IDE drives at the moment and that the gui is in german.
