零磁道处于硬盘上一个非常重要的位置,硬盘的主引导记录区(MBR)就在这个位置上。MBR位于硬盘的0磁头0柱面1扇区,其中存放着硬盘主引导程序和硬盘分区表。在总共512字节的硬盘主引导记录扇区中,446字节属于硬盘主引导程序,64字节属于硬盘分区表(DPT),两个字节(55 AA)属于分区结束标志。
本文通过原理分析,提出了一种解决硬盘零磁道物理损坏的方法。
This paper proposes a solution to repairing the hard disk with its 0th track physically damaged. An analysis or principles is also given in it.
硬盘软故障的数据恢复主要可以从以下几个方面入手:主引导区恢复、分区表恢复、DBR修复零磁道损坏的修复以及文件误删除的数据恢复。
