Since I updated my iMac to OS Sierra my 2TB G-drive won’t go to sleep anymore when the Mac goes to sleep. It keeps spinning. Before update it worked fine. The drive is connected with a thunderbolt cable and it is used as Time Machine (backupdrive). Someone knows a solution for this problem? In preferences Mac the option ‘put harddrives in sleepmode (when possible)’ is on.
I’m having the same issue and am looking for a solution. Were you able to resolve this? Thanks.
Hi,
No still no solution. WD does not respons as well. Bad for such a big company.
By design our drives are actually not supposed to go to sleep ever. Sometimes due to changes made by Apple with newer OSes it changes the behavior of our drives. If you attach a drive over Thunderbolt then it tries to play to the rules of the OS. If it is attached via USB/FW then it pays more attention to our controller.
Oke Rudi’s, Thanks for your reply.
Maybe it’s an idea to place this on your website. I looked there, but couldn’t find this solution (USB instead for Thunderbolt).
To keep de drive spinning is not a problem for me, but doesn’t it shorten the lifetime of the drive?
Thanks.

Hi Rufus,
My mac is configured to turn of the external drives (if possible) and is connected with Thunderbolt. I will try an USB cable and see if it works.
I have rather that the drive stops after put the mac in sleep mode.
