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.

tadas@X_shadow_X:~$ eject cdrom
umount: /mnt/cdrom: device is busy
eject: unmount of `/dev/sr0' failed

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.

well don't know how to say in right English language but i will try. sometimes my cdrom stack's (he try to read something all the time but he cant do it ) and my linux then works wherry wherry slow, i have to log out with ctrl+alt+backspase and later reboot because after message unmounting remote file system's (something like that ) he stops never endless stupid reading.

heeeelppppppppppppp
how to kill that f*****g cdrom

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)
