I have an R4 and a 2GB Kingston micro SD. I was playing it for a little bit, then an hour later, when the R4 booted up, it told me there was an error in the micro SD. I tried again and again, nothing. I tried to view the files on a computer, it can't read them. I've examined the micro SD, there doesn't seem to be anything wrong with it... No scratches or anything, but it's dead. Is there any way to get it to miraculously work again? If not, (sigh) recommend me a new micro SD and a place to buy it cheap. Thanks in advance.
