Access recognition

So my computer recognizes the “wd smartware”: for some reason… now that I have registered my MyBook, it doesn’t come up, the smallest light that shows power is on, but that is it… I have 1/3 of it filled with variety of important-to-me stuff and now i can’t access any of it that wasn’t already pulled onto my desktop prior to the registration …

what the heck!?

Hello,

What’s the model of your drive?

Is it plugged into a wall outlet directly?
