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
