缺陷硬盘数据恢复新技术中的影子方法

Shadow Technique in the New Technology for Disfigurement Hard Disk Data Resumption

论述了缺陷硬盘数据恢复的最新技术——影子方法.介绍了影子技术的实现方案.同传统的磁盘镜像技术相比,该技术不是单纯地创建磁盘镜像,而是通过一定的算法组织影子盘的数据,只有成功读取过的数据才会在影子盘上建立相应的影子,以后读取缺陷盘时会优先从影子盘上读取,减少了缺陷盘的读取次数,从而对缺陷盘起到了很好的保护作用.

This paper discusses the latest technology of disfigurement hard disk resumption： shadow technique, which is different from traditional disk suite technique, and introduces the implementing scheme of shadow technique. Not only does the shadow technique create disk suite, but also organizes shadow disk data with some algorithms. Only if the data is read successfully will shadow be created. When reading disfigurement disk, shadow disk will be read firstly so the number of reading disfigurement disk will be reduced. So disfigurement disk is protected commendably.
