how to use hdparm
 

could somebody tell me how to use hdparm to save battery time?

i installed it with the KDE frontend but that does not work, only in terminal. and i don't understand nothing about using the command line...

if you have the "man pages" installed
man hdparm
you really need to read this yourself, so you can set it up how you
need it......
hdparm -i /dev/hdx will give you alot of info about a particular drive so you can set the flags properly..

thanks for the reply, i just read the man pages but even if i choose the right flags how do i make hdparm to start automatically everytime i boot in order to extend the battery time a little?

I cannot tell you which settings to use, you need to find out yourself (not all hardware is the same).

Here are 2 usefull links that will get you going (explanations + examples):

man hdparm will show you all options and their meaning.

Hope this gets you going.
