+=== Powermode settings ===
+Your Harddrives may have set a power level, that allows spindown. I personally would not let your harddrives spindown, because every start brings your harddrives mechanics nearer to death. In Fact there is not very much worse than spinning up and down every few minutes for a harddrive with physical discs.
+To change that, create the following file:
+<file>
+pcserver2023:/usr/lib/udev/rules.d # cat 85-hdparm.rules
+ACTION=="add|change", SUBSYSTEM=="block", KERNEL=="[sh]d[a-z]", RUN+="/sbin/hdparm -S 0 -B 128 /dev/%k"
+</file>
+That way, your harddrives will stay up all time.
