添加的 HDD 从 /dev 中消失

前几天我突然停电了，当时我正在执行一个脚本，该脚本正在通过网络将大量数据写入我的服务器硬盘。重新启动机器时，我再也看不到该驱动器（它不是启动驱动器）。我已将驱动器取出，并尝试使用 USB 硬盘读取器从中恢复数据。

当我插上电源时，它会发出正确的声音，当它旋转完毕后，我跑去ls /dev/sd* 拿

/dev/sda  /dev/sda1  /dev/sda2  /dev/sda3  /dev/sdb  /dev/sdb1  /dev/sdc  /dev/sdc1

该磁盘是 sdc1 - 所以我尝试安装：sudo mount /dev/sdc1 /media/usb/但是我得到mount: special device /dev/sdc1 does not exist- 当我尝试时sudo fdisk -l我得到以下内容：

即 sda/b 没问题，但没有 sdc 的迹象，当我尝试ls /dev/sd*

/dev/sda  /dev/sda1  /dev/sda2  /dev/sda3  /dev/sdb  /dev/sdb1

sdc 已经走了

关于如何检索该磁盘的数据，您有什么想法吗？我并不关心如何保存磁盘，但确实需要检索数据

答案1

您可以尝试使用 scalpel 或 testdisk 之类的程序。这些程序会梳理您的驱动器并查找 JPEG 或 PDF 等文件签名。因此，如果您的数据具有特定签名，这可能会有所帮助。Windows 上还有许多其他数据恢复工具可以提供帮助http://pcsupport.about.com/od/filerecovery/tp/free-file-recovery-programs.htm
