未检测到 DVD？

当我使用 Kubuntu 12.04 将 DVD 插入驱动器（在笔记本电脑上）时，无法检测到 DVD。驱动器取出 DVD，我能听到它咀嚼了一会儿，然后就什么都没有了。甚至弹出 DVD 也变得很麻烦，我需要在启动时这样做，否则操作系统不会允许我弹出。一周前，Kubuntu 12.04 可以很好地读取和安装相同的 DVD。

编辑：因为我能够从 CD 启动，所以我可以放心地认为该问题不是硬件问题吗？

我怎样才能解决这个问题？

答案1

为了能够解决问题，您必须确定问题：它是硬问题还是软问题？

您的 DVD 播放器是通过 USB（内部）还是 pci 连接的？您应该能够在终端中lspci或给出的输出中看到它lsusb。如果它不再出现在这里，则可能是硬件问题。

最后一件事：由于您的计算机是笔记本电脑，您应该能够移除 DVD 驱动器并将其插入另一台笔记本电脑进行测试。这可能是一个不错的开始，可以知道问题是出在软件还是硬件上（我个人认为是）。

希望这可以帮助，

答案2

在控制台终端输入以下命令：

sudo eject /dev/cdrom2

如果它正常工作，那么您的麻烦是由于以下事实：由于某种原因，cdrom 被检测为第二个 cdrom，并且您遇到了错误。

您有各种 cdrom/dvdrom 吗？或者 USB 硬盘？
