我正在尝试将图像文件复制到外部硬盘。文件名类似于“ 2020-03-25 09:21:27 624.jpg”。我之前已将类似的数据集复制到 Windows 10 中的同一硬盘。但是，当我尝试在 Ubuntu 18.04 中执行此操作时，会显示以下错误。我也尝试过从终端复制。是什么导致了此错误？
以下是输出cat /etc/fstab && cat /etc/mtab

答案1
按照评论中的建议创建一个没有空格的目录作为挂载点：
sudo mkdir /media/rangika/MyBook
使用记录安装您的驱动器/etc/fstab。编辑它：
/dev/sdb1 /media/rangika/MyBook ntfs permissions,defaults 0 0
然后使用命令挂载它sudo mount /media/rangika/MyBook。
但更好的方法是使用 UUID 而不是/dev/sdb1。使用sudo blkid | grep sdb1命令获取它。在我的系统上它看起来像：
$ sudo blkid | grep sdb1
/dev/sdb1: UUID="0ca03411-7a3c-4b99-b134-f53c85065339" TYPE="ext4" PARTUUID="4e24c763-01"
您应该设置您的 UUID：
UUID=0ca03411-7a3c-4b99-b134-f53c85065339 /media/rangika/MyBook ntfs permissions,defaults 0 0
如果您将某个驱动器连接到系统并且该驱动器将获得其他名称，则需要 UUID：不是/dev/sdb，而是/dev/sdc。
