Hard disk clicking when idle

This seems to be a common problem for Hitachi hdd (see Problem with hard drive clicking - ThinkWiki). I don’t know how to disable that setting, the suggestions are for other distros and I couldn’t find one for openSUSE.

I just tried laptop-mode, it seems to provide a good answer. Also powertop. But…is that all?

Check the driver power management and drive load cycle count;


smartctl -a /dev/sda |grep Load_Cycle_Count
