Wake on lan - mode keeps disc spinning

When in wol-mode my hd in networkspace 2 keeps spinning, even if de spindowntime is set to 2min30sec. (hdparm)
out of the mode, in normal active mode, my disc stops spinning after the time i set.
with the 'hdparm -Y' in ssh, sometimes it works, sometimes not.
My disc got hot, because it was running 24/7
any ideas?
