This actually isn't strictly about hacking, although that is where I found the issue first. I have a wii and have upgraded to the newest FW (4.1u). I have tried 5 different SD cards, with different files (photos, softmod files, etc). No card I have will show up in the wii, anywhere Data Managment > Channels> SD says the card in the slot is not usable Photochannel > Card is not usable Even the main SD browser on the home page gives me that. 5 different cards (SanDisk For Wii 2gb SD , Lexar 128mb SD, Kingston 2gb SD, Canon 32mb SD, Noname 256mb SD). I have tried formatting these with FAT and FAT32. I have used the SDformatter program. All of these read perfectly fine on both PC's that I have tried. What is even stranger is that when I insert the cards into the Wii, it gives me the sound notification and light up SD card on the home page saying that it sees the card. Its just when I try to access it that it tells me it is not usable. Any ideas on this? I'm stumped and have search the web up and down. Should I reformat the Wii at this point? Everything else works fine.
