I have 3 raid arrays - one of which is built with (5) ST6000NM0024 6TB
drives.  The drives idle sleep and heads auto park - and removing them and
setting it to off individually still did not work.  The enclosure I use has
no way for me to turn it off either, so I just make sure I am writing to
the array every 30 seconds and the "clunk" stays gone.  dd in the
background writing to the same file over and over.   In hindsight, I should
have left them JBOD and used linux to raid them where I could have smartctl
them on each boot, but oh well.  Once you copy that much data to them, it
really becomes inherently expensive to back it up - which I am not going to
do for media and lab machines.

My other 2 arrays (WD for one and Hitachi for the other) do not idle sleep
and park heads.  It is fairly annoying knowing I am wearing out the drives
sooner than need be and also my vendor of choice for enclosure (formerly)
and raid functionality does not seem to care, but it is what it is..  Just
remember - "Enterprise Capacity" does not mean "Enterprise" class with the
newer Seagates :)
