我正在尝试使用 SATA 转 USB 适配器从 SATA 磁盘恢复数据。在我的 Windows 笔记本电脑上，该磁盘运行良好，直到主板坏了。当我插入 USB 插头时，驱动器被正确检测到。这是 dmesg 的输出：

我还可以在 fdisk 中看到该驱动器及其分区：
root@samsung:/mnt# fdisk -l
...
Disk /dev/sdc: 320.1 GB, 320072933376 bytes

/dev/sdc3 27469824 625139711 2390679552 7 HPFS/NTFS/exFAT
但是当我尝试挂载分区（无论是哪一个）时，出现错误：
root@samsung:/mnt# mount -t ntfs /dev/sdc2 old_disk
NTFS signature is missing.
Failed to mount '/dev/sdc2': Invalid argument
The device '/dev/sdc2' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?
不知何故，所有分区上的 NTFS 似乎都坏了。有什么办法可以恢复我的数据吗？
我还尝试使用 GParted 查看驱动器，但它根本无法识别驱动器上的任何分区。
我正在使用 Ubuntu 14.04。
答案1
我最终使用 testdisk 从旧磁盘复制我需要的文件。Testdisk 显然能够很好地读取分区。
我必须使用最新版本的 testdisk (7.0)，而不是 6.14，因为当我尝试读取最重要的参数时，6.14 一直崩溃。
