Missing /dev/cdrom and /dev/sr0

"ls -al /dev/sr*"
bash: ls -al /dev/sr*: No such file or directory

I cant read any CDs and have no idea why.

dmesg would help here. You do have udev right? Are you sure the drive is getting power and the data cable is firmly plugged in? Do you have another OS (not a virtual machine) on that PC that works? If the above fails, can you try the drive in another PC?

paleksic@phalanx ~ 0 $ pacman -Qi udev | head -n2
Name           : udev
Version        : 135-1

Are you sure the drive is getting power

Yes. I can hear drive gets the disc spinning and i can see when the green LED flashes and then goes steady

and the data cable is firmly plugged in?

I can't tell you that because CDROM is integrated in laptop. And there's a problem with the warranty if i try to open laptop

Do you have another OS (not a virtual machine) on that PC that works?

No, just arch linux here

IMO looks like its dead

Re: Missing /dev/cdrom and /dev/sr0

If your drive is something like a pioneer dvrtd08, and/or your laptop is a sony, try having a cd in the tray at boot. If the device shows up (most of the time) with a cd in the tray at boot, then you are also the victim of wacky hardware. There was a debate on the kernel mailing list over whether or not to detect this behavior and work around it, but I believe they decided it wasn't worth the hack.
