Hi. I would like to share my experience with modifying the AAM (Automatic Acoustic Management) setting on my Seagate Barracuda ATA IV 40GB model ST340016A hard disk.
I used the IBM tool suggested to me by quokked in this thread
which can be downloaded here
from this webpage.
I have no IBM hard disks in my system. The Barracuda is the only disk and attached to the ATA100 Promise controller on my Asus A7V mainboard. The software created a boot disk for me. I booted with the disk and was able to use the dos based GUI to test and set the AAM settings on the Barracuda. When I tried the "view temperature" option the GUI told me I could not do so because it was not an IBM disk so the software is aware of the make of your disk and should work on non-IBM disks. I tried the IBM tool before trying the one mentioned by teklan as I figured IBM would have better quality control.
The 'loud' mode on the Barracuda is noticably louder, but that's the seek speed, not the "idle whine" which I figure is what's really annoying as the idle whine is high pitched. The louder seek sound is low pitched; sounds a little like popping corn in a microwave.
I tested my 'loud' mode disk in the Sandra
benchmarking software and the disk did show an increase in performance of 15% based on Sandra's results.
