Our WD Passport drives (10 drives comprising 3 editions of mostly 4GB 2.5" spinners) are meant for retrievable archives and for backups of the 5 Windows computers on our LAN.
I had hoped and expected that they could be connected via an Anker 10-port Hub to a Caldigit Thunderbolt 3+ docking station attached to a stationary laptop.
But … none of the drives will sleep despite having been set to do so 10 minutes after last usage.
Caldigit says that hubs are not a supported configuration.
Should I conclude from this that the 10-minute scenario is not a drive-located setting that the drive itself enforces? Or is it dynamically governed by Windows-based WD software? Or is it dynamically governed by Windows itself, having once been informed of the sleep setting?
Does a drive need to be connected directly to the Windows host in order to sleep? Will it not sleep if connected to a hub? The drives are visible to WD software regardless of docking station or hub.
Is there a command that can be issued to a drive to make it sleep? Will it wake automatically when requested to fulfill a tasked request?
Is there any way to make drives attached to a docking station or hub sleep according to set parameters?
BTW, all computers are latest Win10Pro.
