After Mojave upgrade my external drive (USB) stop and start spinning every 10 minutes.
It stops and start again immediately.

No matter if I use ite or not, it still do it.

"Put hard disks to sleep when possible" not enabled.

Don't some external controllers have their own power settings? Which specific drive is it?
