HDDs, or more amusingly called, “spinning rust”, store data by flipping the magnetic polarity of tiny domains on the platter to north/south poles which represent 0/1.

There’s a minuscule energy difference that equates to a mass change via E=mc², but it’s on the order of 10^-18 grams for a full drive, utterly negligible.
