What sd card do you recommend for ctgp

Im wanting to install ctgp on my Wii but the sd card "cannot be used" even though it's set up to how all the guides say what s card do you recommend

Details:
2gb elite pro memory card (blue)

Formatted to fat16

Unlocked

i personaly use a 32GB SDHC card on FAT32.

It's probally not FAT32/MS-DOS (FAT).
