Question

我是Ubuntu 13.10的新手。由于某些错误，我登录后会显示黑屏。我想备份USB闪存盘中的重要文件。所以我登录了虚拟终端，以便我可以复制这些文件。

我不会通过USB磁盘启动。我只需要将本地目录中的一些文件复制到我的USB磁盘中。我该怎么做。

请帮帮我。这是非常重要的人。提前致谢。

Answer 1

写

sudo fdisk -l

它将显示所有硬盘驱动器，包括USB记忆棒。（的/ dev /东西）

如果尚未安装，您可以将其安装到/ media / {无论你想要什么}

您可能想要检查它是否已经自动挂载（这应该是Ubuntu的情况）给出

sudo mount

好的，我看到你在那里度过了难关，所以我举个例子。我目前没有USB棒，但我有一个外置硬盘。我将向您展示如何识别它的安装位置：

sudo fdisk -l

你可以看到我有2个物理驱动器（sda和sdb）。正如您所见，/ dev / sda已分区，其中一个分区是可引导的。这表明它是Linux用作文件系统的硬盘驱动器。第二个驱动器/ dev / sdb（320 GB）似乎是我的外部硬盘驱动器。我可以从它的大小（320 GB）和文件系统（HPFS / NTFS / exFAT）验证它 - 你的USB记忆棒可能有这样的文件系统。

然后我会检查我的硬盘是否自动安装：

sudo mount
/dev/mapper/mint--vg-root on / type ext4 (rw,errors=remount-ro)
proc on /proc type proc (rw,noexec,nosuid,nodev)
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
none on /sys/fs/cgroup type tmpfs (rw)
none on /sys/fs/fuse/connections type fusectl (rw)
none on /sys/kernel/debug type debugfs (rw)
none on /sys/kernel/security type securityfs (rw)
udev on /dev type devtmpfs (rw,mode=0755)
devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620)

none on /run/shm type tmpfs (rw,nosuid,nodev)
none on /run/user type tmpfs (rw,noexec,nosuid,nodev,size=104857600,mode=0755)
none on /sys/fs/pstore type pstore (rw)
/dev/sda1 on /boot type ext2 (rw)
binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,noexec,nosuid,nodev)
systemd on /sys/fs/cgroup/systemd type cgroup (rw,noexec,nosuid,nodev,none,name=systemd)
//share/ee_groups_hst/PaCo_Ath on /mnt/share type cifs (rw)
gvfsd-fuse on /run/user/1000/gvfs type fuse.gvfsd-fuse (rw,nosuid,nodev,user=milonaki)
/dev/sdb1 on /media/mike/WD External type fuseblk (rw,nosuid,nodev,allow_other,default_permissions,blksize=4096)

您可以看到/ dev / sdb1安装在/ media / mike / WD External。如果此命令的输出未提供包含/ dev / sdb的行，那么我应手动安装外部硬盘驱动器。
