well i have a 2 of the exact same 32GB cards (they are actualy 29.4GB though), and the one i use on the red card (with no emuNAND partition) is 29.4GB, and the one with an emuNAND partion is 27.4GB... so im going to say its exactly 2GB (but my emuNAND also has about 1 or 2 game patches, so it may be 1.8 or 1.9GB, but i think 2GB is acruate as the updates were only like 1050 blocks added together, and that doesnt seem like much) Whoops! forgot that game patches are stored on the non-emuNAND partition! so yeah, 2GB is right.
