Something is waking up my _unmounted_ drives

I've set my drives to spin down automatically after 30 minutes, as per instructions on the wiki. However, while they do spin down, they woken up some time later - even though they are NOT mounted. I've also tried spinning the HDDs manually using

hdparm -Y /dev/sdb

but they are also woken up some time after.

I tried searching and all results that come up state that it must be udisks polling for S.M.A.R.T. data. udisks used to have a way to disable polling via udev rules, but according to this, udisks2 does not have this option anymore. One comment on that bug report also states that the whole polling was moved to the kernel, so it's not udisks2 that is at fault. Alternative results state that smartd could be the cause, but it's not running on that PC.

Any suggestions on how to troubleshoot this? The wiki article on hdparm/udisks does not mention any troubles keeping the disks spun down.
