Noiseless shutdown + Kubuntu 7.04

Probably you have a normal ATA drive in your hardware that used to be called 
hda. Due to a newer kernel all hard drives are controlled with one driver 
that is not yet fully suitable for normal ATA drives (your disc is called sda 
in that case) The driver SHOULD set everything automatically, but there are a 
few problems for a lot of people.

Acoustic management is one of these settings that may not be set in the best 
way. Until now there is no cure for this, we have to wait for a kernel 

I hope this explained  it a bit.
