硬盘故障、诊断和修复

Question

我的笔记本电脑出了硬盘故障。500磁盘。因此，我将不得不更换磁盘并尝试恢复用户数据。磁盘大约4岁。不确定磁盘损坏有多严重。我用Smartcontrol工具做了磁盘检查，磁盘是通过USB端口通过扩展外壳连接的。结果：

Complete error log:

SMART Error Log Version: 1
ATA Error Count: 272 (device log contains only the most recent five errors)
    CR = Command Register [HEX]
    FR = Features Register [HEX]
    SC = Sector Count Register [HEX]
    SN = Sector Number Register [HEX]
    CL = Cylinder Low Register [HEX]
    CH = Cylinder High Register [HEX]
    DH = Device/Head Register [HEX]
    DC = Device Command Register [HEX]
    ER = Error register [HEX]
    ST = Status register [HEX]
Powered_Up_Time is measured from power on, and printed as
DDd+hh:mm:SS.sss where DD=days, hh=hours, mm=minutes,
SS=sec, and sss=millisec. It "wraps" after 49.710 days.

Error 272 occurred at disk power-on lifetime: 8932 hours (372 days + 4 hours)

问题是，在重新格式化之后，我能继续使用这个硬盘吗？它是只损坏了磁盘上的数据，还是损坏了物理磁盘本身？如果可以进一步使用，我应该如何格式化这个磁盘来修复损坏的扇区？

Answer 1

若要增加从该磁盘恢复数据的机会，应立即停止使用该磁盘。现在卸下它。当您的新磁盘到达时，启动一个普通的Linux发行版，以命令提示符，并像这里描述的那样，将旧磁盘恢复到新磁盘上。记住:不要从旧磁盘上挂载任何文件系统，以免造成进一步的损坏。

至于你关于通过格式化来“修正”它的问题--没有这样的东西。一旦磁盘濒临死亡，就无法修复它。是的，您可以继续“使用”它，但我看不出您如何能够信任它与您的数据。你也许可以把它改装成啤酒杯垫。
