摘要： 对现有的各类硬盘保护卡从技术和性能两方面分析,提出了一种基于端口陷阱技术的硬盘保护卡设计方案,该方案通过在用户级VxD(微软称为VSD,即VendorSuppliedDevice)中链入对硬盘和CMOSI/O端口的陷阱服务,采用扇区映射技术,从而可以做到在已知的最底层达到对硬盘分区和CMOS数据的更完善和更彻底的保护,具有比现有同类硬盘保护卡产品更强的实用性和更好的兼容性。

Abstract: This paper discusses the merits and disadvantages of many hard disk protecting cards,devises a new project of hard-disk protection based on hook-port function and sector mirroring technology.The project has more compatibility and can be put into more practices because of the even perfect protection for HD division and CMOS data from invalid damages.
