This behaviour still seems to be present in 17.04. I have a secondary drive (ST3500418AS) that is isn't mounted and should remain asleep. It doesn't go to sleep unless I force it with "hdparm -Y /dev/sdb". There is something that happens every 10 minutes that will wake up the drive.

I think there is something wrong with libatasmart because just checking the state seems to change the state (Heisenberg?). Running "hdparm -C /dev/sdb" will actually wake the drive up.
