新款联想 x220 笔记本电脑，配备 Windows 7 Pro，规格如下。我想将磁盘备份到我的服务器，但我需要知道 W7 fs，它是什么？
$ sudo mount -t ntfs /dev/sdb 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?

USB-SATA 适配器 - 建议将新硬盘连接到我的 *ix 笔记本电脑，https://superuser.com/a/387134/114739
我正在使用这些 SATA 至 HDD 2.5 英寸适配器这里和这里，买了两件但两者似乎都可以工作，至少在 Ubuntu 和 Windows 中自动安装可以正常工作。

答案1
您可以使用将整个驱动器克隆为图像文件dd，甚至可以压缩它以节省空间：
sudo dd if=/dev/sdb2 | bzip2 >~/old-disk.img.bz2
如果你有pv，你甚至可以得到一个进度条：
sudo pv /dev/sdb2 | bzip2 >~/old-disk.img.bz2
答案2
你想使用NTFS-3G，注意3G。
这应该可以解决问题：
$ mount -t ntfs-3g /dev/sdb2 /mnt/point
我经常使用它在 Debian Squeeze 下安装带有 Server 2008 R2 虚拟硬盘的外部硬盘。
答案3
mount 命令应该有 /host 和 /Windows，就像这个 /host/Windows/。试试看。
