A typical scenario:
I'm looking for a previous version of a document/presentation that was saved on a CD. After not finding it on CD #1, I right-click on /mnt/cdrom, in Konqueror, select Eject and instead of the CD being ejected I get an error message that says that it can not eject the CD because the device is busy or the device is not mounted etc. If I then manually eject the CD, Konqueror will not read it (it displays the content of the previous CD) or list some files and folders with garbage for names. The only way I can then read the next CD is to reboot.
I've even tried (as root and su root) to unmount the CD using umount /mnt/cdrom , umount -f /mnt/cdrom , umount -l /mnt/cdrom , umount -f -l /mnt/cdrom with basically the same result.
Could be many reasons you can't unmount... If Konqueror is in /mnt/cdrom you won't be able to umount. Also there could be a process running that is holding your cd captive... Here is an example of a process holding me from unmounting my cdrom.
# umount -f /mnt/cdrom
umount2: Device or resource busy
umount: /mnt/cdrom: device is busy
umount2: Device or resource busy
umount: /mnt/cdrom: device is busy
Whoa! KenCaz, that fuser routine gavi me a WHOLE lot of numders, and when I started to kill them, I killed my system and had to reboot! And I've enabled supermount with supermount -i enable and now Konqueror doesn't even read the CDs. It mounts them only when I log in. I do have icons for the drives on my desktop, showing them as mounted drives.
Hmm, must have killed a critical process!!! My sympathy...
Well, supermount should only mount your CD when you insert it. If there is one in at boot it will mount it. It senses when you have removed a CD or Floppy and unmounts the drive. Konqueror, however, should not have anything to do with mounting. Once a CD is mounted you should be able to navigate to /mnt/cdrom and view contents. If you eject the CD and are still in the /mnt/cdrom folder you may have to use F5 to refresh Konq's file list.
If you dont' like Supermount you can disable like this:
