  [URL] only 1 spot for a drive adding another is not an option. use a dock for the other drive [URL]       [IMAGE]    
Hi - I am trying to install my old hard drive from my Dell computer as a second in my new Inspiron 3880.  It is the same type - my question is i know to attach the second drive to the cable going to the first drive but do i need an additional blue cable to drive power and if so where would it connect to the motherboard?  Thank you
