![无法安装 DVD 外部硬盘](https://linux22.com/image/1206374/%E6%97%A0%E6%B3%95%E5%AE%89%E8%A3%85%20DVD%20%E5%A4%96%E9%83%A8%E7%A1%AC%E7%9B%98.png)
我的外置 DVD 硬盘无法被笔记本电脑识别。最初,只需插入 USB 电缆即可自动识别。以下是终端告诉我的内容:
me@me-thinkpadx1:~$ wodim --devices
wodim: Overview of accessible drives (1 found) :
-------------------------------------------------------------------------
0 dev='/dev/sg0' rwrw-- : 'ASUS' 'SDRW-08D2S-U'
-------------------------------------------------------------------------
然后:
me@me-thinkpadx1:~$ sudo mount /dev/sr0 /media/asus_dvd/
mount: /media/asus_dvd: no medium found on /dev/sr0.
然后再次:
root@me-thinkpadx1:/home/me# dmesg | tail

我觉得“开机或设备重置”这条消息在这里至关重要,但我不知道如何正确恢复设备并让它再次工作。
值得注意的是,驱动器响应该命令:
eject /dev/sr0
另外(不确定是否相关)我查看了 /etc/fstab 文件,看起来像这样(我删除了注释行)
UUID=fccb78f2-f2ca-47e9-82df-d0d9c4582725 / ext4 errors=remount-ro 0 1
/swapfile none swap sw 0 0
谢谢!

您可以尝试使用 GNOME 磁盘实用程序检查是否检测到驱动器,如果检测到,则检查 DVD 光盘是否包含任何可读分区。
