无法检测或检索此外部硬盘中的文件

我正在尝试恢复外部 My Passport 硬盘。当然，插入后什么也没有发生。

我在插入硬盘之前和之后输入了命令ls /dev/ | grep sd，列表是一样的。此外，您可以看到检查时存在一个真正的问题，当sudo fdisk -l插入此硬盘时，该过程会冻结并且无法完成，但插入正常工作的硬盘时，该过程可以正常工作。

我该怎么做才能尝试恢复文件？

asudo dmesg | tail -n 50显示：

答案1

[11078.910649] buffer_io_error: 498 callbacks suppressed
[11078.910650] Buffer I/O error on dev sdc1, logical block 814254, async page read

这表明这是硬件故障。修复此问题的唯一方法是去硬件维修店，看看他们能否更换损坏的部件。

答案2

TL;DR：USB2 电缆可能仍然有效

我的“My Passport”（WDC WD10TMVW-11ZSMS0）也遇到了类似的问题。在某个时候，它开始变得不稳定。它能够安装，但一分钟左右后，它开始产生 I/O 错误（Buffer I/O error，Failed to get diagnostic page 0x1等等）与您的非常相似。Smartctl如果在设备连接后几秒钟内运行，诊断就非常清楚。

将原来的 USB3（宽 MicroB）线换成从手机充电器上借来的 USB2（窄 MicroB）线后，我得到了速度慢但稳定的连接，并且能够在一夜之间恢复数据。
