Well, maybe it depends on the individual disks how they behave. But for 
my small sample size of two internal laptop disks and one external disk 
there was no spin down. And BTW, for the internal disks i tried it with 
the Kubuntu versions 10.04, 14.04 and 16.04, so the Kubuntu version 
doesn't seem to be important.
