![我的电脑无法识别/安装 CD 和 DVD](https://linux22.com/image/985416/%E6%88%91%E7%9A%84%E7%94%B5%E8%84%91%E6%97%A0%E6%B3%95%E8%AF%86%E5%88%AB%2F%E5%AE%89%E8%A3%85%20CD%20%E5%92%8C%20DVD.png)
我sudo lshw -C disk
得到了
*-cdrom
description: DVD-RAM writer

*-medium
physical id: 0
logical name: /dev/cdrom
我sudo mount /dev/sr0 /dev/dvd
得到:
sudo mount /dev/sr0 /dev/dvd
mount: /dev/sr0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so.
当我在启动过程中按下 Esc 键时(DVD 位于托盘中),其中一条启动消息显示:
I/O buffer error in /dev/sr0 at sector 4096
有人知道问题是什么吗?
更新 1:我已经完成了建议的事情如何安装所有现有的媒体编解码器?- 只需要两个额外的软件包。因此我的电脑在这方面已经是最新的了。
但是我现在sudo mount /dev/sr0 /dev/dvd
再次尝试,然后dmesg
:

我认为“混乱扇区”是指 DVD 上的 CSS 加密 - 我还需要安装一些东西吗?
更新 2:使用 VLC 及其“打开光盘...”对话框,现在可以正常工作。如下所示:
sudo mount /dev/sr0 /dev/dvd
mount: /dev/sr0 is write-protected, mounting read-only
mount: mount point /dev/sr0 is not a directory
dmesg | tail
[ 1378.434161] UDF-fs: INFO Mounting volume 'PLATOON', timestamp 2000/09/24 06:26 (1000)
...但是 DVD 却没有出现在任何地方。我无法导航到 DVD。
答案1
这个问题是由我借的一张有缺陷的 DVD 引起的(我家里通常没有 DVD)。
到目前为止,我正在使用全新安装的 Ubuntu 16.04,并且 CD 或 DVD 都没有问题。(我只需要提醒自己libdvd-pkg
在全新安装后进行设置。)
谢谢您的意见!
