By no means. You may need specialised equipment to extract the data, but you can generally recover anything that was recorded on a hard drive even after reformatting/overwriting etc. The police do that sort of recovery quite a lot when they bust people for trading in child porn and the like. If your drive contains or once contained military secrets, then in the USA and probably anywhere in the West, standard disposal procedure is that the drive be completely overwritten with specific patterns of random data several times, and then taken to a secure facility where the whole thing is literally stamped flat and chewed into small lumps of scrap.
