I had to look around for this and people who leave their PC's on 24/7 or media center might be interested in this:
I tried it on my older 120gb Western Digital SATA drive and it worked well. It does slow the drive down but usually it makes it signifigantly quieter.
Quoted from whiic on the storagereview forum:
Here's three links to Hitachi Feature Tool (version 1.99):
Windows boot diskette creator download
Boot diskette image for non-Windows systems
Bootable CD image with FTOOL
It works both on IBM/Hitachi drives and non-IBM/Hitachi drives. Of course Advanced Power Management (APM) cannot be configured on non-IBM/Hitachi drives simply because those drives doesn't have that feature (it impossible to implement APM without load/unload technology and others use it only in 2.5" and smaller form factor drives).
Seagates AAM setting cannot be configured with FTOOL. It's not a bug in the software, it's simply how Seagate wanted it to be. (I still don't get WHY they don't allow users to reconfigure it. It makes no sense.)
I have also tried SilentDrive. It a software that allows to change AAM in Windows, no boot diskette required, no reboot required, no installation required (just run the EXE)...

I'm having some problems configuring SATA drives (mobo integrated controller, SIS Raid) with it, but it can set the AAM mode for PATA drives.
Hitachi FTOOL is more compatible with SATA drives.
