does anyone know how to get the fourth drive form in KHII? i've beat the game, and i'm stumped as to where to even look to find it. i'm at level 52, with 88% journal completion if its any help.

thanks in advance.

no man, I was pretty far in the game and then MGS3 substinence corrupted the data somehow

you dont really "find" it, it sort of just happens after the fight scene with Roxas at Memorys Skyscraper. Just use your drives and it will happen on its own, then you can choose when to use it.

Like Uknown said it's random. If you're leveling up your drives you'll get it soon.
