Hi there, I've been hearing that HDloader wont work on ps2 compatible PS3s stating that it's an incompatible console, but has anybody tried this method?

Format the ps3s HDD alloting either 10GB or everything but 10GB to the other OS, then download PS2 tools from the PS store and try out HDloader.

Has anybody tried this?? Because the PS2 tools is used to allow the ps3 to use some of it's hard drive to the HDD running ps2 games, so if anybody's tried this plz tell me stating wheither it works, I believe it COULD work but i so dont have it yet and dont wanna if it wont work.
