Claims (1)
- 一种计算机硬盘数据快速保护与恢复方法,该方法包括以下步骤:(1)遍历硬盘分区表;(2)遍历每一个FAT16和FAT32分区的FAT表,生成标志位数据集;(3)根据标志位将整个硬盘虚拟为“原有数据区”(所有Oldinfo的集合)和“自由空间区”(所有Free的集合)两大部分;(4)截获原有的BIOS中断向量INT13h,挂接新的INT13h中断,对所有经过INT13h的读写盘操作进行新的“映射”处理,然后交给原来的BIOS中断向量INT13h进行数据读写,以避免“原有数据区”被破坏;(5)如果要恢复原有数据,只需重新初始化标志集;(6)如果要保存当前数据,只需根据标志位的改变将被搬移(经“映射”处理过)的扇区中的数据拷贝回原处即可;在步骤(1)中,找出当前硬盘上的所有分区,逐一将各分区的起始柱面数、磁头、扇区及总扇区数登记在数据结构PartitionDisk中;在步骤(2)中,如果FAT表项为“0”,在标志集中用Free标记;否则,用Oldinfo标记。
