It seems the old "power nap" options are gone in Monterey (maybe sooner; I only recently upgraded from an older Mac). My external drives are constantly spinning up when my Mac Studio is asleep. I have a studio apartment and this is often distracting overnight. Is there any way to prevent this? (I don't want to shut down the computer as I do a lot of work on it and like to jump back to where I was the previous session.)
Mac Studio
Is there any utility on your mac that runs constantly, like email? Could that service be interacting with the external hard drive? Is there an automatic backup utility that does its work overnight? Is there an Apple update service that runs during the night?
Things to ponder.
Open /Applications/Terminal and paste in this command:
pmset -g log | grep -i "wake from" > ~/Desktop/wake_log.txt
It will list everything that is waking the Mac. Paste a snipped of the report in reply. It will help identify what is waking the Mac. In my case a Logitech external mouse was doing it. It could be a particular external drive, etc.
Thanks, James. Here are some of the log entries from today:

Do you have email in your outbox that is failing to send.?
No, not that I can see; the Outbox is not visible — if I recall correctly, it's hidden unless and until there's an email to be sent.
I read another discussion earlier that may have had this issue but no resolution except some just stopped using sleep function. Many just auto shutdown at night and auto start in the AM.
