the only way to make the hard drives sleep is to put the fan on low Great, this helps! However, HDD temperature has to be monitored until a real fix has been published. BTW: 30 Watts difference may seem to be not much, but with 24/7 this sums up to 260 kWh, which is not cheap, at least here in Germ...

Same here, it was working w/o problems until this 4.2.18 update.
TerraMaster F5-421, 1 SSD, 4 HDDs.

Really a pity, because 45 Watts makes a different compared to 15 Watts before with only one wakeup once a day.
