I have Mac Mini Mid 2011 with macOS 10.13.5 with a data drive. When I wake up at night, the drive is running. I ran fs_usage
and was surprised to find macOS accessing the drive a lot.
How do I stop macOS from spinning the drive, except when accessed by a human, or at least not at certain hours when I sleep? Can Spotlight/macOS be configured to lay off the drive at night?
