Why do my 3 external HDDs go to sleep after a while?

[Legolas8181]

I have had external drives before and they were always awake but I have 3 connected to my laptop right now (two 3TBs and one 1TB) and for some reason if one is not used for a while it goes to sleep.

To save power.

OK but how do I stop it? It can be quite annoying when I wanna do other stuff and then have to wake it up

Not sure if this will work but here are two options to try:

Option 1 Disable USB selective suspend setting:
Go to Control Panel, Click on Power Options, Click on Advanced Settings, scroll down until you see USB settings, click on the + beside USB settings and then click the + beside USB selective suspend setting and change from enable to disable.

Option 2 Using Device Manager:
Go to Control Panel, click on System, click on Device Manager on the left, right click on a USB hub and then click on Properties, look under the Power Management tab and deselect "Allow the computer to turn off this device to save power". Not sure which USB hubs this needs to be done to or if it is all of them. You could try them one by one until the drives no longer "sleep" after not being used for a while.

I did both the options you said and the HDDs still go to sleep

Sorry, but I guess it can't be done.
