I have two 5TB external Seagate HDDs connected to my PC by way of a powered USB hub. In Seagate's Dashbpoard, I have set the external drives to sleep after 1 hour. But they sleep within a few minutes, and I find myself annoyed by having to wait for spin-up time to access the drives. The drives often spin up anyway, causing slow-down in PC performance. Is there a way to get Dashboard to work, without bypassing the hub? Or is there a better alternative?
