The DLNA server is on. What I am trying to do is access my video files stored on a external hard drive attached to my iMac. Without the need for the iMac to be on or the need to unplug the drive and attached it to the WD Hub. Thanks
I misunderstood you. If that's what you want to achieve, you can't do that with your current device. You can do that if you replace your external drive with a NAS.
