我的笔记本电脑上出现了硬盘故障。 500GB SATA 磁盘。所以我必须更换磁盘并尝试恢复用户数据。磁盘已有 4 年左右的历史。不确定磁盘损坏有多严重。我使用 Smartcontrol 工具进行了磁盘检查，磁盘是通过 USB 端口通过外部外壳连接的。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)
When the command that caused the error occurred, the device was active or idle.
After command completion occurred, registers were:

那么问题来了，这个硬盘重新格式化后还能继续使用吗？是仅损坏磁盘上的数据，还是物理磁盘本身损坏？如果可以进一步使用，我应该如何格式化该磁盘以修复损坏的扇区？
答案1
为了增加从该磁盘恢复数据的机会，您应该立即停止使用该磁盘。现在卸载它。当您的新磁盘到达时，将普通 Linux 发行版启动到命令提示符，并将旧磁盘 ddrescue 到新磁盘上，如下所述这里。请记住：不要从旧磁盘挂载任何文件系统，以免造成进一步的损坏。
至于你关于通过格式化来“修复”它的问题——不存在这样的事情。一旦磁盘即将报废，就无法修复它。是的，您可以继续“使用”它，但我不明白您如何信任它来处理您的数据。你也许可以将它改造成啤酒杯垫。
