Once cd is in it won't umount or eject. This is crap.

RHLinuxGUY · 06-16-2005, 05:07 PM

Whenever I put in a cd I can take it out or umount it. It always says cd in drive is busy. What kind of crap is this. This has been happening on 2 different computers. I won't put it on any others if this is how it will be about cds. Any possible solution?

--EDIT--
I always make sure I have no terminal open with it browsing the /cdrom or a file manager, file managing it.

I would guess that you have something accessing the drive.

You can use fuser (man fuser if you need to) to find out who or what is accessing the
drive. You can also use fuser -k /device to just kill the process using the drive. Maybe
not the best solution though.

Hope that helps.

You cannot unmount/eject a busy device. Period. I use KDE so the following might not apply to you @ you didn't mention your distro or desktop. I have experienced Konquerer keeping the device busy for a little while after I closed all the Konquerer windows. I have also experienced Konquerer stopping me from unmounting/ejecting a device even though I was not looking at the directory anymore. The cure has always been to close all Konquerer windows. Other programs might have the same behavior.

Well I'm using ubuntu. And gnome.

i had the same problem. eventually i just had to reboot the pc because it wouldn't spit out the damn cd. even doing ctrl-alt-bkspc did nothing to end whatever was accessing the drive.

pretty annoying

Code:

umount -l /dev/whatever

Would unmount that device, even if it is busy.

you can always force it out with a paper clip

If you do not have applications using or viewing the files on the drive it may be a problem with some sort of auto mounting. Not an uncommon problem. The usual solution is to disable that function and do manual mounts. I thought distros were getting better with this though.

RHLinuxGUY · 06-24-2005, 07:09 PM

how do you disable automount on Ubuntu?

angkor · 06-25-2005, 05:07 AM

Dunno if it does what you want, but you can go to:

System->Preferences->Removable Drives & Media

and uncheck the automounting options.

Hey,

Yea, I've noticed that debian-esq distro's do strange things with CD's sometimes. I find the following combo fixes most of them

Code:

umount /dev/cdrom

(do it with sudo if you really want to assert yourself)

and getting the cd out of the drive is as easy as using the command

Code:

eject

(again, try sudo if nothing else helps)

It's strange I know, I've learned to accept it since the apt package manager still makes ubuntu/debian much better than other distros (IMHO, of course).

I use xfce4 desktop

nautilus take advantage of hal, it may mount and open the drive automatically. I don't know how to disable that yet.

btw, I use rw,user,noauto in my /etc/fstab, my cd drive is in /dev/hdc w/o scsi emulation (and I hate the slow io/cd performance in this system)
