I have a Pixtor SanDisk 64GB MicroSD. I loaded about 10 games on it, and they loaded fine. Then, later on, I added 2 more. But when I plugged the card in and opened up DiskWriter, only 3 of the initial 10 games showed up. I then pulled out the USB and plugged it back in, to which I saw 1. Unplugged it, and replugged it, and saw all 10 again. So what's the issue here?
