Try to kill the MBR (here with 2 GB).
sudo dd if=/dev/zero of=/dev/mmcblk0 bs=1k count=2m
Then have a look at it (and create a new partition, this you can also do at Windows with e.g. 'HP USB Disk Storage Format Tool 2.2.3'... I don't think you should use miniTool/CreateMini.exe)
sudo cfdisk /dev/mmcblk0
If you will do it at Linux, you have to format the partition
sudo mkfs.vfat /dev/mmcblk0p1
Last but not least: sd formatter https://www.sdcard.org/downloads/formatter_4/
