A compound and method for rendering a hard disk drive forensically unrecoverable includes a solution comprising cerium ammonium nitrate, hydrochloric acid by mass, and water. When applied to the surface of a platter, the compound sufficiently disrupts or corrupts the platter such that not recovering the information previously stored on the platter is not possible using known data recovery techniques.
