OK, this confirms that at the end it is kernel issue. You should really report it to kernel folks as true solution must be implemented in kernel driver.
So there are two issues - (initial) spin up and permanent stream of "change" events. To workaround the latter - try disabling periodic device polling in kernel:
echo 0 > /sys/block/sdc/events_poll_msecs
...
both methods did not work, yet.. but I did not reboot yet.. I don't
Well, I expect this does not require reboot. Can you confirm that the value is still 0?
