Comment 478 for bug 59695

Thanks ethanay, I had exactly the same two problems as you!
Personnally I've put "hdparm -B 254 /dev/sda" even in battery mode because this "click" sound is driving me crazy. My HD temperature looks OK (42°C).

I'm not sure the problem is 100% solved thus, because I still hear a much fainter "click" sound, which is happening every 1 second approximately, and I also hear my disk spinning quite often without any reason...
