当我运行 blkid 时,NTFS 驱动器未显示在 fdisk -l 中,无法挂载驱动器

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。

fdisk -l节目

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
