Topic: Hard disks wake up under win 10

The system is installed on ssd both all software and operation happens on it, but is some more old hdd which are very rarely used as . Therefore I installed  switch-offs of disks on pair minutes, ungeared  and an automatic defragmentation that they permanently would sleep and did not rustle. But all the same periodically they turn on.  during this moment activity of disks through resource monitor - calls to disks it is not fixed. What to do?
