如何挽救分区表丢失后硬盘中的数据

由于病毒破坏主引导扇区中的分区表，使硬盘无法启动。用软驱启动机器亦不能进入硬盘。通常只有利用ＦＤＩＳＫ和ＦＯＲＭＡＴ重新分区并格式化，果硬盘中原有信息完全丢失。本文依据分区表的构成及ＦＤＩＳＫ的工作原理，提出不破坏硬盘原有信息，恢复硬盘功能的方法。即使原来主引导扇区没有备份，这一方法也行之有效。附录中详细介绍了具体的操作步骤，并通过实例说明。

INFORMATION RECOVERY IN A DISK WITH PARTITION TABLE DESTROIED BY VIRUS INVASION

Due to virus invasion, the partition table in the master booting sector of the hard disk maybe destroied,rendering it unbootable. Rebooting the system via the floppy disk drive.the disk remains to be invalid,Usually this disk should be recovered by using FDISK and FORMAT,while the information stored in is inevi-tably erased. Based on the structure of the partition table and the operation of the FDISK,COM,a process to fix the hard disk, keeping all the data unaltered,is described in this paper. Evenif the partition table backup is lost,this method is still valid.Illustrative,examples are detailed in the appendices.
