After turning on my Wii after a couple months, I tried opening the Homebrew Channel. No apps showed up. I pressed 1 and tried to select the SD card.
And suddenly...
Exception (DSI) occurred!
In the System Menu, attempting to see what's on the SD card displayed the dreaded "The device inserted in the SD Card Slot can't be used" message.
I was using a SanDisk 16 GB microSDHC card with a microSD to SD adapter (also SanDisk).
Formatting and copy-pasting the files didn't help.
