METHOD OF PROTECTING HARD DISK THROUGH DISK BLOCKING

摘要

PURPOSE: A method of protecting a hard disk through disk blocking is provided to manage the hard disk through the disk blocking, and to install a disk protection interrupt handler while performing a POST(Power-On Self Test) process of a computer, to have control over input/output processes of the hard disk and control a BIOS(Basic Input/Output System) interrupt handler, so as to protect the hard disk before booting an operating system. CONSTITUTION: A hard disk protection system performs a POST process to install a ROM program, and snatches an interrupt INT13 to have control over a disk protection interrupt handler(11). The hard disk protection system controls operations of a hard disk(3) as handling hard disk input/output processes through every INT 13. The hard disk protection system temporarily intercepts system DOS operations, and performs a protection operation for a ROM program driver by setting up a protection processing routine in a predetermined location of the hard disk(3). The hard disk protection system distinguishes a protection area from a non-protection area by concentrating data of the hard disk(3) on one position, and generates a backup file.
