I have two cord with an external DVD/RW I bought some time back. There's
two cords the one I use with USB 2 on my tower to the DVD/RW and looks like
data but it's power too.

    This second one IDK what it's for. I goes to the "power" interface on
the DVD/RW. I guess I don't need it. But idk what would. Is it to get your
DVD/RW to move faster or something?
