Assuming you have at least 4 GB of free hard drive space, make a backup of that right away. Careful not to dd over your data, of course! Something like "dd if=/dev/sdb1 of=~/myusb.bin" I'm assuming you can do this since clearly the computer recognizes the existence of the device. Once you have an image of the data, it might be easier to try mounting or playing with the image file rather than the USB stick itself? That's what I'd try, anyway.
