You find the dubious disc in Mt. Mortar. Go to Mahogany town and go left to the first entrance you see for Mt. Mortar. Go in and go straight (I suggest bringing some max repels to avoid battling a lot of pokemon) until you see the first rock climb. Use rock climb then go back and left until you see another exit and go through it. Go right all the way to the small rock and press A. You should find the Dubious Disc. Hope this helped.
Note: The Dubious Disc is to be given to Porygon 2 to make it evolve into Porygon Z.
You find the Dubius Disc in the P2-Labratory in pokemon white. Hope that helped :)

You can't find it from the wild, only trade it while it holding a Dubious Disc.
You find the dubious disc at the p2 laboratory on route 17-18. You find the upgrade on route 15, very close to white forest. You have to beat a Pokemon ranger and have strength to push a boulder and get to it.
The Dubious Disc in Pokemon Diamond and Pearl is the item used to evolve Porygon 2 into Porygon-Z. To do so, you must attach the Dubious Disc to Poygon 2 and trade it to another game. Once the other person receives the Pokemon, it shall instantly evolve into Porygon-Z.
