Following on from my previous comment, the drive is most definitely spun up again by udisks2 polling at 30 minutes, even though udisks2 doesn't read the SMART data at this point. I recompiled udisks2 to use a far more reasonable polling time of 24 hours and now the drive stays spun down like it should.
