挽救硬盘数据

Recover the Data in the Hard Disk

本文通过对硬盘各级分区表的深入剖析,揭示硬盘上下级分区表中各分区信息之间的内在关系。提出在硬盘第一级分区表遭受毁坏情况下,用第二级分区表中的分区信息来修复第一级分区表中分区信息的方法,在没有任何备份的情况下使硬盘的各逻辑盘(除第一逻辑盘C外)中的数据得以挽救。

This article explores various levels of hard disk partition table, and displays the internal relationship of partition information between two levels of hard disk partition table. It's argued that when the first hard disk partition table is damaged, the partition information of the second partition table can be used to recover that of the first one. Therefore, even if it's performed without backup, the data in every logic disk (except the first logic disk C) of hard disk can be recovered.
