Exclamation How unmount working cdrom?


Sometymes i need to log out and reboot my cpu besause my cdrom stack's (stops working). I try this

tadas@X_shadow_X:~$ umount /dev/sr0
umount: /mnt/cdrom: device is busy
or
root@X_shadow_X:/home/tadas# umount /dev/sr0
umount: /mnt/cdrom: device is busy

but as you can see.

another question how to make my cdrom act like in windows, when i press eject button on my cdrom it opens, and automatic unmounts

and the last question. In /etc/rc.d/rc.modules
see the documentation in /usr/src/linux/Documentation/sound/,
# and /usr/src/linux/Documentation/Configure.help.
but
adas@X_shadow_X:~$ ls /usr/src/
rpm/
tadas@X_shadow_X:~$ cd /usr/src/linux/Documentation/sound/
-bash: cd: /usr/src/linux/Documentation/sound/: No such file or directory
Where can i find Documentation for sound. i use Slackware9

Sorry for English

Try using the eject command to eject the CDROM.

As far as mounting/unmounting with a press of the eject button on the drive, that is done through a daemon called autofs, I think. This package comes with the Slack 9 ISO, but I myself can't figure out how to configure it. The stuff I have found on google hasn't really helped. Anyone with more information, please post it.

Do you have something like Nautilus open, that could be using the CDROM drive? Or maybe you were listening to a CD, and the program didn't end properly, and is still occupying the CDROM device. Do a ps -e and see if there is anything like nautilus, or something else that looks familiar like a CD-playing program.

try

hdparm - w /dev/sr0

(this will try reseting/unsticking your cdrom but beware

hdparm -w : Perform a device reset (DANGEROUS). Do NOT use this option. It exists for unlikely situations where a reboot might otherwise be required to get a confused drive back into a useable state.)

then try remounting it


does your cdrom work fine under windows?

if it works fine under windows, then try turning the cdrom's dma off in linux with

hdparm -d0 /dev/sr0


if you have the same problem under both windows and linux, then it's clearly a hardware problem.



PSi have the same problem with my dvd, clearly a hardware problem. until i buy a new one, i take out it's power supply and remount every time that it hangs, but i wouldn't suggest it to anyone)
