I've seen disks that don't spin down when set with a timeout using hdparm -S, that do spin down when given an hdparm -y command, (I.E. they spin down immediately).
Does hdparm -y cause your disk to spin down?

Good idea.

Good.

No.

Test whether hdparm -y works - it should spin the disk down immediately.
