Degaussing applies a strong magnetic field to a magnetic hard disk, disrupting the recorded magnetic data and typically making the drive inoperable. Factory resets and reformatting are logical clearing methods, while cryptographic erasure depends on properly implemented encryption and complete key sanitization. NIST describes factory-state reset as a clearing method and cryptographic erase as key sanitization that makes decryption infeasible.
