摘　　要：为提高硬盘固件修复成功率,简化硬盘固件修复的工作流程,分析了硬盘固件的基本工作原理与硬盘固件区的基本结构,介绍了包括固件模块替换法、备用固件区替换法、固件模块重定位法和热交换法在内的传统硬盘固件修复技术的概念,阐述了硬盘固件区虚拟技术的实现原理以及操作细节,并在此基础之上将该技术与传统硬盘固件修复技术进行了全方位的比较,通过一系列对比实验表明了该技术在日常数据恢复工作中的优势和实用价值。To improve the hard disk firmware repair success rate and simplify the workflow, the basic working principles of the hard drive firmware and the basic structure of the hard disk system area are analyzed, the concepts of the traditional technolo- gies, including module replacement, backup system area replacement, module remapping and hot swapping, are introduced. Then the principles of the hard disk system area virtualization technology and the details of operation are described. Based on theses, a full range of comparison between this new technology and the traditional technologies is carried out. Finally, the advantages and practicality of this technology in routine data recovery business are demonstrated by a series of comparative experiments.
