cdrom issues

cs-cam · 12-17-2004, 07:34 AM

I'm running GNOME 2.8 with magicdev in Arch Linux 0.7 (2.6.9 kernel) and I'm having probs with my dvd drive. It's there, CDs with a filesystem automount and work fine, when I right-click the icon and press eject a sometimes get this error.

Quote:

eject: unable to open `/dev/ide/host0/bus1/target1/lun0/cd'

and I won't be able to get the CD out. Today is the first time I've noticed this it has worked fine before. However audio CDs it won't recognise, I put them in and no automount, can't manually mount them, get the bad superblock/fs type/already mounted error and I have a mixed-mode CD here and I can access the files fine but no audio programs will recognise the audio side to the CD. DVD movies work fine I'm reasonably sure, don't have one handy to try right now though but I'm pretty sure they do.

Any ideas as this is seriously bugging me

It's probably something stupid, audio CDs worked fine under Gentoo and my SuSE live cd..

Thanks

and this is at the bottom of dmesg output, not sure if it's relevant

Fixed, probably not via the best method but it works now.

DJ P@CkMaN, please try to say more than the fact that you've fixed the problem. It's far more useful to find out what you've learnt about what could be causing the problem, and what sort of solution you have found.

There's nothing more annoying to a someone who's searching these forums than to find out that someone else has their exact same problem, has fixed it, and hasn't said how.

I am having the same kind of problem myself. Running FC3 and I am curious what you did to resolve the problem. I would really appreciate having you post some details.

I had a similar problem and solved it by using udev instead of devfs.
I never fixed the devfs problem though.
I would like to see the solution also =/
If i could remember the details of installing udev i would post them here but i dont, so google it and im sure you'll find a howto (probably better than what i would have wrote anyway)

I use gentoo anyway so the steps would be a bit different :P

Sorry, just chmodded the device to 0777. That's why I didn't post it because you'd all probably tell me how bad it was

But it's not running sshd or apache or anything like that so I'm not really too scared.

A better solution might be to add your login user to the group that owns /dev/ide/host0/bus1/target1/lun0/cd
