Problem installing NEC-ND2500A

I just bought one of these dvd burners and im having problems getitng it installed.
I took out my cd burner and put the new one in the same spot with the same plugs (the long one and another one with four holes…power?) When I start my computer now… I nothing shows up for the drive. Also, my primary drive isn’t showing up anymore…which i didn’t touch.
