Would like to back up my Samsung 840 EVO 250gb SSD with Win 8.1 to a new internal WD 1tb HD in a new build? It's my first windows build and have NO experience with windows! I had to spend 65 minutes with an Indian Microsoft customer support person because I installed the WD after installing Win 8.1on the SSD and windows thought it was a different system. I think I can work through the partition & format steps but want to set up one partition for back ups & the other for games & misc software. If someone is kind enough to answer, I will need "step by step" instructions as I'm a "computer challenged" 80 year old trying to keep up with the changing world!
