That is something I have never seen. A friend of mine built one from the opposite adapter that allows the 2.5" drive in a normal ide. They should be well under $10.
Get 44 little pins and stick them in the adapter to convert the small female connector to a male and plug it into the laptop. Be certain the pins are long enough and the lengths are consistent. Then plug a normal ide cable into the other end and connect your drive to it.
I don't know if he used the laptop power for the drive or a separate power source. If they are separate, make sure you can ground them together.
Steal a male power connector off a dead cpu fan to get power from the adapter.
