I would just try it and see. Install Cygwin, and then install your
USB card reader with SD card installed. Try and figure out if
the /dev/sdX nodes are created. Sorry, I'm not sure what the
Cygwin command might be ...

To read binary data:

   int fd, len;
   char buf[10];

   fd = open("/dev/sda1", O_RDONLY);
   if (fd < 0) {
     printf("open failed\n");
     return -1;
   }
   len = read(fd, buf, 10);
   if (len < 0) {
     printf("read failed\n");
     close(fd);
     return -1;
   }

   ... mess with your data ...
