First we want to fill up our pendrive with zeroes:
sudo cat /dev/zero > /dev/your_pendrive
After completion we can check if our flash drive is really wiped with zeros by installing and using a text-based Hex-editor:
sudo apt-get install ht
Remember: We trust nobody so we check manually if zeros have been written to the drive. If you see weird characters something went wrong.
sudo hte /dev/your_pendrive
