what do mount and cat /proc/swaps say?  Is your spinning hard drive
mentioned in either?  If you've confirmed there's no active use of
the drive by the above, you might look at hdparm:

 -B   set Advanced Power Management setting (1-255)
 -S   set standby (spindown) timeout
 -y   put drive in standby mode
 -Y   put drive to sleep
 -Z   disable Seagate auto-powersaving mode
