In doing back-up data, we followed the work to be done is to switch to a system running DOS, and DOS command line in the implementation of "fdisk / mbr" command string to try to repair the hard disk of soft failure occurred ; if such a repair method to try is invalid, then we can go online to download and install the hard drive Bad Track professional testing tool to double-check the local hard disk in the phenomenon of the existence of Bad Track, Bad Track If you can not find the hard disk, it can not detect hard drive through the phenomenon is likely to be caused by the logic of failure, the logical solution is to find a Bad Track Repair Repair Tool to re-click the hard disk, only to do so.

在做好数据的备份工作后，我们接下来要做的工作就是将系统切换到DOS运行状态，并在DOS命令行中执行"fdisk /mbr"字符串命令，来尝试修复硬盘中发生的软故障；要是这种修复方法尝试无效的话，我们可以到网上下载安装一些专业的硬盘坏道检测工具，来仔细检查本地硬盘中是否存在坏道现象，如果找不到硬盘坏道的话，那硬盘检测无法通过的现象很可能是逻辑故障引起的，解决办法就是找逻辑坏道修复工具来重新修复一下硬盘，只能这样做了。
