When I put my Mac to sleep for the night, all the external hard drives spin up for a few minutes around once an hour or so which is irritating me. The screen does not wake up. I was wondering if anyone had any suggestions for how to prevent this.
I'm running a 2020 Retina 5K iMac under macOS 12.6.7. In my Energy Saver System Preferences, both 'enable power nap' and 'wake for network access' are UNchecked. 'put hard disks to sleep when possible' is checked.
I wrote a program to (amongst other things) keep my external spinning disks awake during the day and then late in the evening it stops that until morning. Alas, something deep in the OS doesn't play fair.
The program should be (like the Mac) not logging anything through the night.

Sometimes it will go the whole night w/o waking more than once or twice.
(In the "daytime" that log hits 1/hour on the hour as designed).
There are all sorts of things MacOS does behind-the-scenes during "idle" times, Spotlight indexing, Time Machine, update checking, malware checking, etc. being just a few examples. Sleep mode doesn't stop all those things happening. Other apps running will also have things the do.
The simple solution, as someone else said, is to just shut the computer down when you're not using it - there's zero reason for it to be running 24-7, unless it's an internet server that others need to access while you're asleep.
