Well I've been using the same SD card for about a year now, and everythings been working fine up until now. I've changed nothing whatsoever on the SD card! all I did today was turn on the wii with the sd card in, bootmii popped up, and loaded the system menu (4.1U), once I tried to access the HBC, none of my apps were showing up, so I just exited and tried again to no avail. Just being curious I tried to move a save file to the SD and that said "SD Card Can Not Be Used"...So I popped the SD card in the PC,transfered everything off, and formatted with the SD Formatter that Wiibrew describes, formatted to fat, transfered everything back, and the same issue occurs! I don't know if its the SD card or the SD reader in the Wii (as bootmii is able to access it and I can browse the files on it)...any help is greatly appreciated!! thanks guys in advance Wii specs are: 4.1U Cios38 Rev16 Hermes Cios Rev4 HBC 1.0.6 Bootmii IOS/Boot2 SD Card in question is a 2GB Samsung, also have tried a 2GB Pny to no avail.
