I contacted Mark Lord, the main dev behind hdparm, and he had some thoughts.
Among other things, he asked us to clarify whether just unmounting (instead of
unmounting and powering off, e.g. by using 'udisksctl power-off ...') the drive
before shutdown really solves the problem. I'm asking as 'unplugging' can be
misinterpreted and that could lead to misunderstandings. In short, does the
problem occur if you unmount the drive, and then just shut down your computer?
And don't forget to disable your script while testing :)

In my case shutting down with an unmounted drive did not solve the problem. If
it does indeed work in your case then we may have different scenarios here.
Mark had other ideas as well but I'd like to clear the unmounting part up first
to plan the next steps better.
