My Book Live - Never Sleeps - What am I doing wrong?

Thank you for reading.
I have two My Book Live drives (Model AP1NC)
They both used to show a blue LED and sleep when not being asked for data
I have noticed the they both now stay green and I can hear then ‘on’ all the time.
These are my data backup drives so I really only want minimal use of them, They are copies of each other.
The “Sleep” box is ticked in the settings.
These are 3TB units
Firmware up to date : MyBookLive 02.43.10-048 : Core F/W
I have looked at other posts, I hope this info is of use and maybe someone can suggest or help,
Thank you in advance for your time,

Hello there,

Have you tried power cycling the units or resetting them? You can reset them by pressing the button on the back with a paperclip or a pin for 3 to 6 seconds, this will not delete any data so you dont have to worry about losing anything by resetting.

Hi, Thank you - I missed that, So I have tried that and now waiting, time to sleep to will see what the morning brings - Fingers crossed, Will report back, Thank you for the suggestion.

Read my post, something like “mediacrawler the ultimate solution” Google it.

I shut one down, its not needed unless I back up from the other.
After a ‘reset’ it appear to stay blue (sleep) for good long periods of time, that wakes up from time to time but I’m not sure why.
But much better.
(Just got to work out how to wake the other from shut down!)

Funny - Just went green! no idea why but at least it sleeps most of the time now.
Thank you.
