I hear what you say. However, ... it does! O_O
I ran hdparm -iI /dev/sda once from the console and once after I
logged into KDE. As you can see the KDE command shows:
Recommended acoustic management value: 128, current value: 254
and
Automatic Acoustic Management feature set
while the console shows:
Recommended acoustic management value: 128, current value: 128
and
* Automatic Acoustic Management feature set
Also there are some differences at the Security tags at the bottom,
should that make any difference. Both of the commands were run
without /etc/init.d/hdparm being started at boot time or since.
If I run -M 128 the drive goes quiet and stays so surviving a reboot,
until I login into KDE again. So, if KDE switches of the Acoustic
Management for some reason, there should be some way of asking it not
to?
