Abstract: This article introduces the current technical status, advantages and disadvantages of a hard disk protecting card and some particular application software used in hard disk data protection. It also analyzes and gives clues to the programming method of hard disk data protection. The algorithm introduced in this article will protect hard disk data from destruction, except those few viruses with their own particular destructive procedure of INT 13, caused either by improper human operation or by most viruses' invasion of designated hard disk sections.
