It looks like the USB port is not reading the drive correctly. Since this is a microSDHC, have you tried using another adapter to put it in? I've run into a similar problem when I used a different manufacturers adapter on one of my Sandisk cards. (I'm using a laptop, so the card reader is already built into my computer.)
