好像我的 CD 阅读器坏了。这很奇怪,因为“eject”和“wodim”(或 GUI 等效项)可以运行:我可以弹出 CD 并刻录 CD-R - 但无法检查,因为它无法读取任何 CD。
> sudo mount /dev/cdrom /media/cdrom
mount: block device /dev/sr0 is write-protected, mounting read-only
mount: you must specify the filesystem type
> sudo mount /dev/cdrom /media/cdrom -o ro -t iso9660
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
missing codepage or helper program, or other error
(could this be the IDE device where you in fact use
ide-scsi so that sr0 or sda or so is needed?)
In some cases useful info is found in syslog - try
dmesg | tail or so

我确定文件系统是 iso9660(我有此 CD 的 iso 副本作为文件,并且可以将其安装为循环设备)。
我尝试安装一张音频 CD,但出现了同样的错误(与 VLC 相同)。
我不明白我的系统出了什么问题。
有什么方法可以诊断问题吗?
修复它吗?
以前有人见过类似的行为吗?
我非常希望收到您的来信。

系统有缺陷。
重启后解决。
