How to unock the cd drive???

Tarrasque · 07-01-2003, 08:31 PM

Hello everybody.
I have a problem.
Sometimes when I use my DVD reader, the tray stays "locked" (the open button is disabled) even after I close all file browser windows and applications and unmount the device.
I have no idea how to solve this
tThe only thing that works is log out from my seession, but obviously is not something I can do every time I want to change cD
Can anybody help?
Thanks!

I assume you have the correct driver installed? I am not familiar
with Mandrake but the device locking up sounds like a software
conflict somewhere...

Cheers

Happened to me in WinXP dunno what it is, but in my case it happened when the drive couldn't read the CD> I had to reboot and then flip it out of there.

Try disabling supermount.

See man pages supermount for details

What kind of disks does this the happen with?

Have you tried eject -r cdrom from command line? Works in RedHat.

Actually I noticed it happens after I use the KDE cd player.
Whenever i finish listening to the cd.
I'll try investigating this a bit more and disabling automount.

Works great in Mandrake 9.1 too

Maybe there is an process using the cd drive? (and is closed when your session terminates?)

try fuser -v <mount point> to see what processes are using the mount point.

I've read this threat and picked up a few usefull commands but nothing that solves my specific problem. When I type "eject /mnt/cdrom" my main drive is ejected however when i type "eject /dev/cdom" my secondary drive is ejected!! I'm using Mandrake 9.1. If I just put a data (mp3) disc in it auto-mounts however if i put an audio cd in I get an error saying it's locked.

ooh I see. You might want to change /etc/fstab, and your links to device nodes. (the /dev/ folder) I have 2 cd-rom drives aswell, so I'll show you what my configuration works. I hope you find something usefull for you here

* This is a part of my /etc/fstab

Code:

# cd-drives
/dev/cdrom     /mnt/cdrom          auto     ro,noauto,user,exec,owner                      0  0
/dev/cdwriter  /mnt/cdwriter       auto     no,noauto,user,exec,owner                      0  0

* my /dev/cdrom is a link to /dev/hdd
In other words, the secondary drive on secondary ide.
* you might expect my /dev/cdwriter to be a link to /dev/hdc, but instead, it points to /dev/scd0. My IDE cd-writer is also accessable through scsi emulation. (hdc=ide-scsi at the lilo prompt) It's required to use an IDE cd-writer.
