after six months of undeniably perfect operation, my sd card died out on me. what happens is when i pop it in my computer, everything seems normal but when you delete stuff it says "Cannot delete XXXX: cannot find specific file," and when you try to format it, nothing happens. nada. not even that format window that shows your options. using sd formatter from panasonic it says its unsupported. and obviously i can't copy files into it. what a pain. and even if you delete stuff from it, it just keeps popping back when you reinsert it.
