If you're on Gnome: did you try "gnome-disks" utility? - or another
utility if you don't have Gnome? - I found that settings in Gnome
are not necessarily reflected in the ones below /etc. And maybe that's
true even vice-versa ...

And funny enough: I just found I don't seem to even have a
hdparm.conf. But the settings via "gnome-disks"  tell me my (built-in)
head-clicker disk has APM set to 255 ....

​Although I'm not a Gnome fan, I do have gnome-disks,
and again, no matter what I command it to do, my LoadCycleCount
still keeps going up.
And 'hdparm -i /dev/sda'
fully rightly tells me the disk has (amongst other things):
" AdvancedPM=yes: disabled (255)"

​I'm beginning to think that my drive just doesn't support a 'disable' value for APM.
So far my only workaround has been a shell loop that touches a file I don't care about.
