这很可能是这个论坛上问过的最基本的问题，但我找不到任何答案。我在硬盘上安装了 Ubuntu Server，并安装了两个额外的硬盘用于文件存储。安装过程很顺利，添加另外两个硬盘也很顺利。

现在的问题是，我实际上如何访问这些驱动器并将文件放入其中？
我想将电影放入 /media/primarydrive/movies，但当我创建目录并尝试访问它时，系统提示“没有这样的文件或目录”。我需要做什么才能使用这些驱动器？抱歉，文字太多了，但根据我的研究，这些是这些论坛上最常见的两个回复的答案。提前谢谢您。
答案1
如果驱动器已安装，您可以将目录更改为它们吗？
cd /media/primarydrive
如果可以的话，你能为它们创建一个文件夹吗？
mkdir mymovies
（或mkdir /media/primarydrive/mymovies从任何其他位置）
您能否发布文件的内容/etc/fstab，告诉我们安装了哪些驱动器、如何安装以及安装到哪里。
