    Question KWorker (?) keeps spinning up HDs

    I've just set up Ubuntu Server 12.04.3 LTS wtith LAMP, installed Webmin and Samba and every 5 minutes something seems to call a smartctl command so two of the four HDs spin up. I tried stopping all services and cronjobs, but it still happens. According to blktrace the call comes from kworker - but I guess that could be anything then?
