Unable to eject CD. ?HAL problem

I have been ripping some audio CDs with kaudiocreator and am finding that I am unable to eject CDs. This does not happen every time, perhaps every other time. I get a message saying CD unmounted but cannot eject. I am unable to eject by pressing the button on the CD drawer.

The one method I have found whereby I can eject the CD is to su to root and issue

Quote:

eject /dev/hda

I have the cdrom line in fstab commented out.and I am joined to plugdev, etc Running slackware 12. I never encountered this problem in 11.

Any help gratefully received.

Hi,

Did you look at '/etc/udev/rules.d/75-optical-devices.rules'?

Delete the file and restart to see.

from '/etc/udev/rules.d/75-optical-devices.rules'

# Local optical devices rules to make links to your
# optical devices

# These rules were generated by cdrom-symlinks.sh, but you
# can customize them.

# You may edit them as needed.

# DVD drive and you need to be sure they will always be

ENV{ID_CDROM}=="?*", ENV{ID_PATH}=="pci-0000:00:1f.1-ide-1:0", SYMLINK+="cdrom0"
ENV{ID_CDROM}=="?*", ENV{ID_PATH}=="pci-0000:00:1f.1-ide-1:0", SYMLINK+="cdrom"

Note the message about symlinks.

There is probably some app accessing the CD in the background. I had the same issue and couldn't eject the CD until I closed Amarok (even though I didn't access the CD using Amarok at all -- it probably automatically did something when the CD was inserted). I may be wrong though -- I'm just offering the simplest explanation.

Thanks. I will have a look at your suggestions over the weekend. It might prove difficult to sort out because I could not discern a regular pattern to it and because I do not often find myself ripping a pile of CDs like I was last night.

This is curious.

A: I am not mounting the CDs at all. These are audio CDs and I am ripping them to mp3. I do not think there is any problem with data CDs

B: There is no problem with the first CD but with the second CD I cannot open the tray without issuing eject /dev/hda as root.

C: I have configured KDE to 'Do nothing' when I put in an audio CD

D: I am not aware of any other programs accessing the drive

Here is /etc/udev/rules.d/75-optical-devices.rules. I do not think tha it is relevant to the problem

Does the mount command show anything interesting?

I'm also wondering if this is connected to a problem I had. I found via ps that a library - /usr/lib/kde3/kio_audiocd.so - was the problem so I renamed it to kio_audiocd.so.old.

So far so good...

/dev/hda is not mounted

Try renaming /usr/lib/kde3/kio_audiocd.so

Bit of a hack but until the problem is addressed...

I tried that but then kaudiocreator would not rip the CD at all. Some error about ioslave

I have also discovered that

Quote:

killall kio_audiocd

will then let me eject. This command works without su'ing to root.

Ah I use ripperx so yeah it would be a problem for a kde app.
