[SOLVED] Haggis: /dev/sr0 missing

[GekkoP]

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.

computers are weird, I swear I installed stuff using the CDROM on my old tower this week. won't even open the tray now...

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