Bad sectors are small clusters of a hard drive that become inaccessible due to physical damage (e.g., scratched platters) or logical errors (e.g., corrupted magnetic patterns). HDD Regenerator claims to repair physical bad sectors by generating a high-amplitude magnetic signal to restore the magnetic domain.
