Lost control of cdrom

[hannes]

Hi,

I just recently put Kubuntu 8.10 on my new ASUS X83V. I have control over my cdrom drive before I put in a CD. After I put in a CD and try to run Amarok, I have no control over the cdrom. Before inserting the CD, I can open and close the drive by pressing the hardware button on the drive or with the command $ eject cdrom. Then I tried to play a CD. Amarok hangs when trying to play the disk. After killing the program, no command or hardware button will give me the CD back.

I noticed that /dev/cdrom is a symbolic link to /dev/scd0 prior to trying a CD. After the CD is in, this link is no longer there. eject /dev/scd0 doesn't work. Pressing the button doesn't work.

I can still see the cdrom in lshw as:

*-cdrom
description: DVD-RAM writer
physical id: 1
bus info: scsi@1:0.0.0
logical name: /dev/scd0
logical name: /dev/sr0
capabilities: audio cd-r cd-rw dvd dvd-r dvd-ram
configuration: status=open

How do I get my CD out? How can I get this drive to work?
Thanks,
Hannes

Re: Lost control of cdrom

I noticed a little weirdness with KDE3 the other day after burning a CD -- it didn't seem to want to let go of the CD. Eventually the Device>Eject item worked to eject it. There may some issue with the "wodim" driver, or whatever 8.10 is using these days. Mine burns CDs and runs data CDs correctly -- I don't play music CDs much (I rip 'em with KDE3 and save the files).

Have you tried opening Dolphin, and then on the device icon on the left you should be able to right-click and choose "eject" or "safely remove".

The cdrom icon is not present in Dolphin.

If you can open a console window and do

cat /etc/fstab

and post the output, maybe it will show something.

Also, does

sudo lshw

show the optical drive?

see the original post for the output of lshw. Here is /etc/fstab:

Oops.

OK, I just checked mine -- lshw shows:

/etc/fstab shows it as:

/dev/scd0    /media/cdrom0  udf,iso9660 user,noauto,exec,utf8 0    0

So, in comparing one that works (mine) versus one that doesn't (yours), it appears there is nothing different about the mounting arrangement, and we're left looking at the lshw output. I wonder why yours shows "status=open"? That is most likely the source of the error.

Unless it has a pinhole for you to stick a paperclip into, I would think maybe a system shutdown (all the way down and off, not warm restart) might change that flag to "closed".
