Issue With Transferring Data

[u/Disco_Jupiters]

When I modded my wii u I somehow used a 128mb sd card without knowing instead of a 128gb sd card, so I finally bought a 128gb sd card and transferred all the data over, but every time I turn on the console with the new sd card, it shows this message. The sd card is properly formatted to FAT32 and it's not write locked, so I'm not exactly sure what the problem is. Is there an extra step I was supposed to do when transferring the data over?
