external drives turn on regularly...

[fisherking]

i have 2 usb-powered external drives, connected to a (usb-powered) hub, connected to my 2015 macbook pro. power nap is off, 'wake for wifi access' is off... but periodically, the drives turn on, for a minute or so.

anyone know why this might be? and what to do about it (if anything)? just curious about why this happens.

thoughts, info? anyone else notice this behavior?

Check System Preferences to see if the drives are excluded in Spotlight and Time Machine?

i don't use time machine, and i definitely want them indexed in spotlight. does spotlight index when the mac is sleeping??

There is an old Apple Discussion on sleep and Time Machine. It's too old to know if the info is still relevant.

Try these links:

Jame Pond's site: http://pondini.org/TM/Home.html is a great resource for help with Time Machine.

i'll check those links. again, i don't use time machine, it's not enabled... but thanks for the info.

EDIT: both those articles are out-dated, but will google a bit on my own.

Keep Drives Awake is off in Energy Saver too? Is the wording perhaps different like : Allow Drives to Sleep.

What I wrote above is not important - carry on.
