<p dir="ltr">'dd if=/dev/zero of=/dev/sdX bs=1M count=1' as root, against the unmounted drive (not partition) will solve your problem. Of course, you'll have to partition and format after that. Fat and iso9660/ufs store filesystem data in slightly different spots, both near the beginning of the drive. Doesn't help when the filesystem image is purposefully crafted to exploit that fact.</p>
