Hard drives waking up all the time in Monterey. Any solution?

[WilliamG]

Hey all,

I run a bunch of RAID arrays connected to my 2018 Mac mini. Prior to Monterey they’d sleep all day, only waking up for drive checks every 24 hours. Since the Monterey update they’re waking up all the time, and it’s really wasteful, likely to cause premature failure of disks.

Anyone else encounter this, and is there a fix at all?

Thank you in advance!

Same problem here now since, I guess, a Monterrey update.

I did some experiments and it looks like if the Mac (iMac 2019) enters sleep mode, the external drives go to sleep as well, you see a USB hub do the same, but after a minute they wake up again. And after a few minutes they go to sleep again, and the same thing repeats over and over again.

What is happening ?

I killed all background processes, but it doesn't help.

Not sure why the USB/TB ports keep (basically) power cycling, even when there's only a WD My Book HDD attached.

For me my Mac mini never sleeps, so it's nothing to do with sleep mode - it's just Monterey being rubbish.

Here is my workaround:

Monterey Bluetooth wake issue.

In my case it happens when on battery or on AC power - and if I have external disk connected it starts/stops every few seconds. Not acceptable. And of course when on battery it kills it quick. Turning BT manually off before going sleep "fixes" the problem but automation is always better in case...

Some reports suggest that it will be fixed in 12.3

I forgot already replied to this thread. I posted more here:

Western Digital My Book (Duo) drivers & sleep mode

Are there more people with a Western Digital My Book Duo (in RAID0) external drive ? Have the impression it started after a recent Monterrey update. Since a few weeks I notice some strange behaviour: - iMac goes to sleep (iMac 2019) - Drive (via USB-C) goes to sleep - USB (via USB-A) hub is...

Anyone with any further updates or solutions for this? Almost a year later and still driving me insane...

Monterey is pushing Windows ME territory for unreliability. $4000 computer, can't do USB or bluetooth reliably. Awful.
