I have Orico docking station for Internal Western Digital 4TB Black hard disk drive . If i don't use the disk for 2-3 minutes the disk goes to sleep mode . I have disabled in power management setting ,set hard drive to turn off to "Never" and usb selective suspend setting to "Disable". I am not able to work if it goes to stand by if i want access files quickly , have to wait for few seconds for hdd to start spin.
