Fedora在笔记本电脑上未检测到CD磁盘

14

我很少在笔记本电脑上使用CD，但是我记得几个月前也遇到过同样的问题。当我将CD放入DVD驱动器时，什么也没发生。上次没有我做任何事情时就开始了，但我不知道出什么事了。我需要用k3b刻录CD，但是它给出错误“找不到光学设备”。

我的系统是Fedora 20 x86_64。问题：没有安装CD，将其插入驱动器后什么也没发生。

我该怎么做才能解决这个问题？

更新电流：问题：cd和dvd不能正常工作，因为行进时它们一直不稳定，如“插入时不安装”，“插入时安装但随机断开连接” /“随机断开”，断开连接时不可见到系统，我无法弹出磁盘。

昨天我将DVD电影放到驱动器中，将它安装在/ run / media / username / MOUNTPOINT中，并且传送工作正常，然后消失了一段时间，不再安装了，因此我无法从驱动器中弹出DVD。现在就是这样，它仍然在驱动器中，以下是一些现在可以在驱动器上运行的命令：

从上面获取的预期输出是从系统中获取的，而在安装DVD时（通常是成功的），我需要知道为什么磁盘可以随时断开/卸载/消失。

dvd驱动器，磁盘和dvd的行为已安装 /run/media/username/MOUNTPOINT 并正常工作，但是它们可以随时断开连接，而当它们断开连接时，它们不会出现在系统中的任何位置，并且我无法弹出磁盘。

当我合上盖子时，笔记本电脑被设置为“睡眠”状态，这是我在4个小时前完成的，而当我在一小时前撤消它时，驱动器中的DVD已装入/run/media/username/MOUNTPOINT。现在是这样的：

如果CD未被标识，k3b则可能k3b没有足够的访问权限运行。最初，您应该尝试以k3broot 身份运行并验证CD是否正确识别。

看来您所做的一切都可以正确诊断问题。据我了解，它是不良的CD驱动程序，不良的硬件。当您提到“它在没有我做任何事情的情况下上次启动”时，它上次起作用了，但现在是硬件问题。要么可以装入驱动器，但是如果它可以工作一次并且不能再次装入，那么我认为所有这些都将导致硬件故障。

在此U＆L问答中尝试我的技巧：unix.stackexchange.com/questions/110993/…。wodim可能会很痛苦。您还在运行GNOME吗？将DVD插入驱动器时，Nautilus是否不显示DVD驱动器？

— slm

@slm我正在运行KDE，两天前，我插入了一部DVD电影，该电影出现在Dolphin中，如果我将“ df -h”安装在/ var / run / media / username / MOUNTPOINT上，但它一直坐在从那时起，大部分时间都找不到驱动器，也没有安装它，我也无法将其从驱动器中取出。想想我是否重新启动它被检测到。我将磁盘取出几个小时都没有问题。

如果fstab中有与cd / dvd设备相对应的条目，请尝试对其进行注释并重新启动。自动挂载和fstab选项之间可能会有一些干扰。

尝试使用这个。

eject /dev/sr0

因为它将在

eject /dev/sr0如果/dev/sr0不存在，将无法正常工作，问题是ls /dev/sr*报告ls: cannot access /dev/sr*: No such file or directory。

关于查询，执行以下命令并验证输出是否有错误：

$ lsblk
$ lspci
$ dmesg | egrep -i --color 'cdrom|dvd|cd/rw|writer'
$ cdrecord -prcap dev=/dev/cdrom
$ ls -l /dev/sr0
$ x-cd-roas

通常，报告的问题可能是由于以下原因造成的，

CD驱动器未正确连接；
可能需要更新驱动程序；
您连接的端口可能已损坏。

因此，首先，请检查连接端口是否工作正常，还要检查CD驱动器是否通电。

同时更新CD驱动程序。

如果问题仍然存在，则CD驱动器中存在问题。

最后一个命令是否与此相同：en.wikipedia.org/wiki/X-CD-Roast？

这是一台笔记本电脑，我没有将其连接到任何端口。我的问题中已经有了dmesg命令的输出。我不是想这样写CD，而是想弄清楚为什么有时我的CD和DVD有时不挂载，有时又挂载但可以随时断开。我的输出中已经有ls命令。

Linux的CD驱动程序？我想说，您的硬件很有可能是脆弱的，或者您的连接是脆弱的。我要考虑的三件事是：1）光盘驱动器没有牢固的连接（通常它们是可移动的），并且在发生混乱时随机断开/重新连接；2）光盘驱动器内部损坏，内部某个地方的连接不稳定或固件错误等；3）电源问题。我怀疑这与驱动程序或软件有关。

我已经经历过几次了。我为您提供一系列问题和建议。

fedora的版本是什么？
笔记本电脑的CD-ROM是否滑出？
引导到PC时它会闪烁吗？
您是否用yum更新了硬件？

尝试插入带有数据的CD，看看它是否弹出。

如果您的CD已正确初始化，则应弹出。

我没有笔记本电脑了，但问题仍然显示出关于该主题的一些不错的信息，谢谢您的回答！
