No CD drives

I don't have any accessible CD drives:

ls -l /dev/{cd,dvd,scd,sr}*
ls: Zugriff auf /dev/cd* nicht möglich: Datei oder Verzeichnis nicht gefunden
ls: Zugriff auf /dev/dvd* nicht möglich: Datei oder Verzeichnis nicht gefunden
ls: Zugriff auf /dev/scd* nicht möglich: Datei oder Verzeichnis nicht gefunden
ls: Zugriff auf /dev/sr* nicht möglich: Datei oder Verzeichnis nicht gefunden

dmesg output:

How can I get the drives reenabled ?

Re: No CD drives

When posting on the forum, please prepend your commands with LC_ALL=C so that the output is in English.

Google shows that there are many people that report their drives (often DVD-RAM - like yours) randomly missing - try to reboot and cross your fingers.

Re: No CD drives

All of them are missing by default in Arch now. It was done during a recent udev upgrade.

/dev/sr0 too?
https://wiki.archlinux.org/index.php/Be … M_symlinks symlinks to /dev/sr0, but the device is missing for OP.

Do you have an optical drive? If so, do you have /dev/sr0 by default or did you have to tweak something?

@kopiersperre
What's the output of

cat /proc/sys/dev/cdrom/info

?

Looks like we suffer from the same problem: https://bbs.archlinux.org/viewtopic.php … 60#p985360

Re: No CD drives

lolilolicon saved my life, finding a solution: it was enough to connect the dvd to another sata port.

Hope this helps.
