Nintendo DS Lite, Acekard 2.1 is the hardware. I inserted my MicroSD card into the USB adapter and plugged it into my computer as usual. I started to delete some files off of it to clear up space, but halfway through the deletion process, it all suddenly closed. I attempted to open it again, but I get a "PLEASE INSERT A DISK INTO DRIVE H:" error. When I load it up in my DS, it shows my menu and even my custom skin, but no games (because I deleted them all.) I tried in different ports, even on different computers. It still gives me the same message. I switched the MicroSD card for another and still encounter the same error, which leads me to believe that it's an adapter problem. Anybody else experience this, or know what I have to do? At this point, I'm thinking about just buying a new adapter, but I'm not really sure. Thanks in advance!
