本文档详细介绍了如何模拟MBR扇区故障的实验过程，包括添加硬盘、分区格式化、备份MBR、模拟故障、然后在救援模式下恢复MBR，以确保系统能够正常启动。

实验：MBR扇区故障
1.实验案例演示：
1.添加一块硬盘
2.分区格式化
1.
[root@ns1 ~]# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x9c831ce6.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.

Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

WARNING: DOS-compatible mode is deprecated
