As far as I remmeber there is a program, located at the ibm website, 
with which one you can adjust the power management of your IBM hard 
drive. I used it myself once to get rid of this speeding up / down 
issue. You are right, it is a power management feature. So I just set it 
to no power save in there, that kept the drive at constant sound.

Hope that helps...
