CD-ROM won't eject after unmounting

exit3219 · 06-27-2005, 11:42 AM

Quick question:
After I access the cd-rom using KDE, I cannot eject it. I am a non-root user, member of the 'cdrom' group, using Debian Sarge. If I open Konqueror, select the CD-ROM in Devices and choose 'Eject', it sais 'Eject /dev/hdc failed.'
If I press the CD's eject button (on the hardware, I mean), it doesn't do anything.

I only can eject the cdrom if I logout from KDE.

How can I fix this?

Thanks.

what happens if you type:

Code:

eject /dev/hdc

at a terminal, both as a regular user and as root??

The eject button will not function as long as the CD is mounted. The eject command will unmount the CD but nothing can be accessing the file system. Be sure to close Konqueror or switch it to another directory and close any terminals that are accessing the drive prior to ejecting.

there is also a bug in konqueror that causes this...something to do with the side navigation bars...it's on kde.org bugtraq

Thanks for the answers.

If I run eject as a normal user, I get

Code:

eject: unable to eject, last error: Invalid argument

and the CD doesn't come out. If I run eject as root, it comes out, but throws the same error message (but at least it does come out).

Here's my /etc/fstab for /dev/hdc:

Code:

/dev/hdc        /media/cdrom0   iso9660 ro,user,noauto  0       0

Here's something else (only relevant parts):

Code:

$ ll hdc
brw-rw----  1 root cdrom 22, 0 2005-06-28 11:50 hdc

/media$ ls -la
lrwxrwxrwx   1 root root    6 2005-06-19 17:51 cdrom -> cdrom0
drwxr-xr-x   2 root root 4096 2005-06-19 17:51 cdrom0		(either it is mounted or not)

$ whoami;groups
exit
exit root daemon bin disk mail news dialout cdrom floppy audio dip src video plugdev games users gdm

As you see, I'm part of the cdrom group, which owns /dev/hdc. Should I chgrp cdrom /media/cdrom0 ?

(I have done a ln -s /media/cdrom0 /cdrom to navigate faster.)

If I do (as a normal user)

Code:

$ mount /cdrom
$eject /cdrom

then it gets ejected. But if I use Konqueror to mount / eject the cd-rom, it works only if I haven't accessed any file from the CD. If I accessed a file and then closed the program that opened it, it sais 'Eject /dev/hdc failed.' and I have to open Konsole, su, and then eject as root. This is not quite cool to do!

Any ideas?

Dear exit3219:

I have the exact same problem, precisely, using Debian Sarge. But fortunately I was able to test this command because I have a second DVD/CD cdrom1 drive. When I type:

eject /dev/hdd

the second cdrom1 drive opens and ejects my DVD. But when I type the exact same command for the first cd drive:

eject /dev/hdc

I get the same "invalid argument" error message. This can not be. What's good for the good is good for the gander. There must be some configuration error somewhere, but I don't know. Will report if I find the answer.
