Hi
I have an IBM X40, and I am not really happy with suse 10.3 and the
powermanagement. Under windows I have almost 50% more time than under suse.
One reason is that the HD does not spin down because the OS keeps the HD
busy all the time and every 30 seconds seems access the drive.

Is there any simple way to change that?

thanks a lot in advance,
Volker
