Automatic Acoustic Management is a feature of most modern hard drives which reduces the seek noise at the cost of performance. 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.
Run silent drive after unzipping the 18K freeware to a location on your hard drive. It should automatically detect your IDE drives and display the drives current setting, it will most likely be disabled. To silence your hard drive you would select the
leise (silent) switch, mittel (medium) means a balance between performance and noise and laut (noisy) means maximum performance but more noise. Click on seek-test after you changed the setting to hear how noisy your hard drive is.
You can change the settings back to default of course and everything will be as it was. The settings you make are saved by the hard drive itself. It might be that your bios is reverting the changes on every start. This would mean that your only option would be to add silent drive to your autostart.
The parameter would look the following:
SlilentDrive -d0 -mo
with -d0 to -d3 identifying the hard drive and -m0 (off), -mm (medium) and -mq (silent)
An alternative that also works with SATA hard drives is Hitachis Feature tool that is also working with most hard drives out there. Hitachi provides a download of a boot disk or iso image of the tool which you have to boot from to use. The great thing about this is that users that are not using Windows XP or 2000 will be able to change the settings with the boot disks.

Holy Crap! I can hear the difference instantly! Thank you so much for turning me onto this great little piece of freeware.
just wanted to drop in and say that your site always has great stuff. I’m honored to link with you!
The GUI is in English. Thanks for another great tool, what paul said is valid for me as well.
The first tool listed also works with SATA drives and it’s cool to verify and change the drive’s settings!
