在 Ubuntu 16.04 中找不到我的 DVD 驱动器

Question

我想你可以说我是一个受过轻微教育的菜鸟（我知道，一点知识是一件危险的事情）。

我的驱动器在 Mint 17.3 中运行良好，但我现在运行的是 Lubuntu 16.04 并且我的 DVD 驱动器还没有工作。我尝试了多张 CD 和 DVD；音乐、数据和空白。

lsblk -f 返回：

NAME   FSTYPE LABEL    UUID                                 MOUNTPOINT
sda                                                         
??sda1 ext4            69fe002a-8d2a-4297-ac0b-272c60c019ce /
??sda2                                                      
??sda5 swap            82575a1c-ca49-4060-b860-d078ad7b54d6 [SWAP]
sdb                                                         
??sdb1 ext4   31GBEXT4 e19d4f79-0600-42c4-8159-77a844544c09 /media/greg/31GBEXT4
sr0          

cat /dev/sr0 返回：

cat: /dev/sr0: No medium found

所以我尝试lshw并得到了这个：

*-scsi
     physical id: 2
     logical name: scsi0
     capabilities: emulated
    *-cdrom
         description: DVD-RAM writer
         product: DVD RW AW-G540A
         vendor: SONY
         physical id: 0.0.0
         bus info: scsi@0:0.0.0
         logical name: /dev/cdrom
         logical name: /dev/cdrw
         logical name: /dev/dvd
         logical name: /dev/dvdrw
         logical name: /dev/sr0
         version: 1.W0
         serial: [
         capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram
         configuration: ansiversion=5 status=nodisc

然后是这个：

$ mkdir ~/dvd | sudo mount /dev/sr0 ~/dvd
mount: no medium found on /dev/sr0

在这一点上，我几乎抓住了稻草。所以现在怎么办？

信息更新：我可以毫无问题地在磁盘中找到它，但是当我在驱动器中有 DVD 时它不显示任何媒体。我已经清洁了镜头，但这从来都不是问题，因为在我安装 Lubuntu 16.04 之前它运行良好

结果 dmesg --level=err,warn

Answer 1

实际上，您的系统确实找到了驱动器并正确识别它，如索尼 DVD RW AW-G540A。您提供的输出表明，困难在于从系统确信为空的驱动器中读取数据，正如您提到的那样。根本原因可能是激光失败（因为您已经清洁了镜头）。如果该设备完全可以修复，则不值得花费维修费用。考虑到年龄，我建议更换驱动器或整个笔记本电脑（如果预算可以承受）。

Answer 2

刚刚完成的部分 - “不要认输”
我有 Optiarc DVD RW AD-7530B (NX02)

1. sudo add-apt-repository ppa:brandonsnider/cdrtools
2. sudo apt update
3. 有 3 个包裹，所以我这样做了：sudo apt-get dist-upgrade
4. sudo apt install cdrecord mkisofs
5. 重新开始

就这样，为我工作，让我很开心，谢谢
