Cable Select jumpers (Article)

[John Prophet]

I was going to post a question about Cable select jumpers on hard drives cause I ran across the question on a test i took recently. Ive never much heard a good explanation of them until I saw this article.
I figured Id post it and then maybe if someone does a search for "cable select" (like I just did), they will run across this article.

I knew that CS was on the jumpers for a reason and I finally got tired of hearing "Oh, cable select??..oh, it doesnt do anything"..lol.

Didn't read the whole article. But it sounds right on! I find I still have the jumpers set to either master or slave. Even though CS would ease my life up allot.
