Depending on your purpose for the adapter, it may never work. Many newer boards have their own IDE channel hanging off a certain way that it won't boot. SATA native DVD-burners are $20-$30 at MicroCenter, might it just be easier to pick up a new one? (For the better part of a decade I've just bought whatever Samsung drive was available; haven't had trouble yet) Many lower-end boards forgo IDE channels altogether; but at the $90-$150 mark, include one that they've added via some third party's controller chip.
