I bought a 2gb SD card. Inserted it into my wii and it saw it I inserted the card into a sub2 media card reader on my mac and it said the drive needed to be initialized so I said ok. I then chose to format as MS-DOS format (same as my USB memory sticks) and then nothing ? Application not responding. I pulled out the reader,, and put the card back into my wii. It now says that it can not read he card in the slot.. My mac continued to lock up whenever I try to format it. Anyone else had a simlar experience. I have to use the mem card reader as we dont have a ny digital cameras that take SD, only compact flash or sony mem stick.
