New WD 6T -- Lost startup CD...what can I do to install?

I purchased a WD 6T My Book. Got home and unpacked it. Left it overnight and when I tried to get it up and running, I found I had somehow lost the install CD. Is there anything I can do to go forward like downloading the information on line? I’ve Goggled the WD sites but cannot find a direct download center that will help. Any information is greatly appreciated. I’m using Windows 10 on a quad core HP.

I don’t remember any My Books coming with CDs, but if it did, it’s all here:

Thank you Sir! Hit the spot…
