the point here is, that i dont want to save electrical power, more to
increase the livetime of my harddisks. All cheap harddrives are build
to run 8 hours and 5 days a week and not more. If you run it 24 hours
a day, the lifetime is decreasing significantly (i think instead of
100 hours you only have 20 hours).

ah ok, that is fine to hear.

thx, i installed it now, with hdparm it seems that i have some problems.
If i send the sleep command with hdparm it is going to sleep but not
automatically if i set the timeout with hdparm.
