Hi, ok this is my first time ever responding to any forum so I hope I help anyone. Now I have a WD MBWE white light 2TB so I do not know if it will work with other drives, and I am using windows 7.
1.First make sure you have a static IP address on your router and computer, if you do not know how to do it, youtube it, very important if not your drive will choose a different IP address everytime.
2.Hold down power button on the hard drive until it turns off.
3.Then unplug the ethernet cable from your router.
4.Then turn on hard drive and plug the ethernet cable into the ethernet port .
5.Wait about 10 seconds just so ethernet is hooked up correctly, then open up WD Discovery program and search for drive it may take a while.
6.While the ethernet is plugged into your computer restart your computer and wait for it to reboot.
7.Next check if drive is still accessable on your computer if it is then disconnect it from your computer and plug it back in the router, wait 10 seconds or more and the files is now accessable.
It worked for me so I am noob too but you know I did a lot of research and checked up on a lot of pages and I did a trial and error hope it works for you because it worked for me and I am no expert in this so you can try or not up to you.
