I am thinking of installing a 2nd hard drive on the pc. I was told that I need to get some jumpers my current hard drive has none on it. What my interpretation of jumper is little pegs that basically dictate which drive is master and which one is the slave. As far as right now I have no clue if my drive that I will buy (bare drive) will have something telling me where to put the jumpers. As far as my current drive I can't see to find that out either. My real problem is these EDA cable i don't get what they are, from what i gather they attach the drives together but are these used along with the jumpers? Any information would be help full i am a new to all of this and i would like to learn. Oh and i did a search for my type of question and found stuff but not exactly what i was looking for so i hope someone can help me thanks.
