Google your problem first. Check the Wiki. Read the existing threads.
It's okay to "hijack" an existing thread, yes! If your problem is not yet covered, open a new thread. To get the quickest possible help, mention the exact release codename in your post (uname -a is a good idea, too). Due to the lack of crystal balls, attach the
output of lspci -nnk if you encounter hardware problems.

I was ripping an audio CD using ripit. All was going well, but then an error occurred (audio cd is full of scratches) and ripit stopped. No panic, I just tried again. Suddenly ripit can't see my cd-rom drive.
So I did:
Code: Select all
~ % eject
Unable to find or open device for: 'cdrom'
Again, no panic. I did:
Code: Select all
~% dmesg | grep CD-ROM
~% dmesg | grep DVD
~%
Oh, ok. So I checked /dev:
Code: Select all
~% ls -la /dev/sr0
ls: cannot access /dev/sr0: No such file or directory
Someone stole my cdrom! Any suggestion?

Does lspci list it? If not, check BIOS if CDROM is actually detected and active.

Btw, because you mentioned the CD is scratched: maybe it helps to use dd/ddrescue or testdisk/photorec to copy the CD first. Then you can still extract its contents and copy/rip/encode.

Ok, I am feeling like an idiot. I shut down this morning, and just booted. Now:
Code: Select all
~ % dmesg | grep CD
[ 1.711153] scsi 0:0:0:0: CD-ROM MATSHITA BD-RE UJ-220 1.00 PQ: 0 ANSI: 5
[ 1.914590] cdrom: Uniform CD-ROM driver Revision: 3.20
[ 1.914770] sr 0:0:0:0: Attached scsi CD-ROM sr0
I swear I didn't do anything.
Consider it fixed. Consider me a hopeless newbie.

Thanks bacon, I'll do that next time.

the more complex the system, the more unexpected the errors.
classic case of rebooting doing wonders :)
