Disk Not Ejected Properly "Macintosh HD - Data"

I have a couple of external hard drives and SD Card in my computer and every time my iMac wakes up, I have multiple 'disk not ejected properly' messages for EACH drive. I had over 25 notifications today!! grrrr

Unfortunately I have the settings disabled, but I still do have the warnings every morning, while I'm on Monterey 12.2.1 (M1 Macbook). I didn't have it when I was just on Monterey, so it's something since the more recent updates.

I've started seeing this issue on my MacBook Pro (Retina, 15-inch, Mid 2015) in just the last couple of days. I'm running Monterey 12.3.1. It appears this version of the OS does not have a "Put hard disks to sleep when possible" option. Any ideas?

Me too.. im getting the same thing

Mac mini (2018)

I have started having this same issue with a MacBook Air (Retina, 13-inch, 2020) since upgrading to Monterey. I also have the same volumes listed as OP.

I've also started seeing this message frequently on my Mid 2015 15" MacBook Pro Retina since updating to Monterey (12.0.1). it doesn't seem to impact it other than the message is annoying.

I spoke too soon - got it again today (first time in a couple of weeks).

Since my system is a desktop, there is no "Battery" System Preference. It is good to have a solution for the laptop folks, though.

Try Energy Saver instead.

There is no "Put hard disks to sleep when possible" or anything else related to disks on the Energy Saver page.

You don't have this:

What Mac is it?

I haven't seen the issue in a while. Perhaps it was resolved in Monterey 12.1?

I have a new iMac 24" M1. Energy Saver does not show the option to put hard disks to sleep. It only has the other three checkboxes.
