摘要:
GPT 分区是目前硬盘普遍使用的一种分区形式，克服了 MBＲ 对分区管理不能超过 2 TB 的缺点。但是由于用户误操作、计算机病毒破坏、突然掉电等因素的影响，使得 GPT 分区被破坏的情况时有发生，从而导致存储在硬盘中的数据丢失。针对这一情况，以 Windows 7 为平台，WinHex 15．08 为分析工具，虚拟硬盘为实验对象，对虚拟硬盘 GPT 分区结构进行分析，通过 DBＲ 的特征值查找并获得 DBＲ 及 DBＲ 备份所在扇区，将 DBＲ 中存储的总扇区数转换为逻辑盘的总容量，以此为依据重建硬盘 GPT 分区，最后通过 DBＲ 备份所在扇区恢复 DBＲ。实验结果表明，当 GPT 分区被破坏后，只要获得逻辑盘总扇区数，便可成功恢复 GPT 分区，从而完整恢复各逻辑盘中的全部数据。
Abstract:
GPT Partition is a common partition form of hard disk at present，which overcomes the disadvantage that MBＲ cannot exceed 2TB in partition management． However，due to user’s misoperation，computer virus damage，sudden power loss and other factors，the destruction of GPT partition occurs from time to time，resulting in the loss of data stored in the hard disk． In response to this situation，based on Windows 7 platform，WinHex 15．08 as the analytical tool and the virtual hard disk as experiment object，we analyze the GPT partition structure． The DBＲ and its backup in the sector are searched and acquired by the eigenvalues of DBＲ． The total number of sectors stored in DBＲ is transformed into the total capacity of the logical disk，based on which the hard disk GPT partition is rebuilt． Finally the DBＲ is restored by its backup in the sector． The experiment shows that when the GPT partition is damaged，as long as the total number of sectors of the logical disk is obtained，the GPT partition can be restored successfully，so as to completely restore all the data of each logical disk．
