Hello I just got a SanDisk 256gb SSD and am wondering how to install it into my computer. I connected the power and sata cables to my drive and motherboard but my computer does not recognize it. I do not want my SSD to be my main drive, which are what all the videos and web searches came up with. All I want to do is add it to my available storage and be able to put games on it. What do I do? or what am I doing wrong? Thank you for your input.
