There are only a few naturally-occurring materials that are magnetic by themselves, without electricity being applied to them to make them into electromagnets. One of them is lodestone. It is actually made of magnetite, but not every piece of magnetite is a lodestone, because not all magnetite is magnetic. To become a lodestone, magnetite has to be magnetized first. We do not know for certain what magnetizes lodestone in nature, but some believe that it is magnetized by lightning, because lodestone is found closer to the surface of the Earth, while magnetite can be found buried deeper. These days, permanent magnets that we use are most often made of alloys. The most strong magnets are made of rare earth metals like neodymium (Nd2Fe14B).
The magnet in this drive is attached to its base plate with a few dots of glue, some little locating nubbins, and, once again, its own bodacious magnetic field. There’s nothing wrong with leaving a hard drive magnet attached to its base plate, if you don’t need both sides of it uncovered. The steel plate makes the magnet much less prone to breakage. NIB magnets are brittle, and flat thin hard drive magnets commonly snap while people are playing with them.
