我无法看到使用 USB 2.0 驱动器连接件连接到我的 12.04 计算机的 750GB 驱动器。该驱动器是从 Windows 7 计算机中拔出的，我只是想从中获取所有信息，以便我可以擦除它并重新开始。

sudo mount -t ntfs /dev/sdb /media/windows
NTFS signature is missing.
Failed to mount '/dev/sdb': Invalid argument
The device '/dev/sdb' 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?
我不确定为什么这不起作用，如能提供任何帮助我将非常感激。
答案1
您可能应该使用：
sudo mount -t ntfs /dev/sdb2 /media/windows
注意 sdb 后面的 2。您尝试挂载整个磁盘，而不是分区。
答案2
使用两个实用程序 photorec 和 testdisk，我发现分区已完全损坏。我能够提取所有文件。感谢您的帮助
