CD-ROM Locked in

Many times when using Linux, I can't open the CD-ROM drive.  I can mount and unmount it all I want, but I can't change the disk!  What is going on?

In linux, you can only open the cdrom drive when it is not mounted.  use the mount command to access the drive.  Then, when you want to change it use the umount command.  Then you can open the drive and change disks.

When I use the unmount option from the right click menu on the CD-ROM icon in KDE, the green light in the icon goes off, but sometimes the drive still will not open
You may want to try to use umount at the command prompt rather than the menu selection.  KDE can be quite flaky at times (mine gets random core dumps from time to time for no apparent reason) so you may want to circumvent K for some tasks.
