I just installed it, and I can't play ps2 games on it. Am I not clear about the ps2 system data I don't really understand what it's for. I am guessing playback on the ps3 for ps2 game data (which should be game discs?)

The PS2 System Data is the partial PS2 Emulator for the PS3. Unfortunately, it is only useful on the older 80GB models that had 4 USB ports and came bundled with either Motorstorm or Metal Gear Solid 4 (and the 60GB PAL region PS3s). THese had part of a PS2 in them, but not all of it, and used the emulator for that part they were missing.



The 20GB and non-PAL 60GB models had a whole PS2 in them, so they didn't need this.



The 40GB, newer 2 USB 80GB, and 160GB don't have any PS2 hardware in them at all, so the emulator doesn't replace all that is missing.
