Hmmm....

Ever tried the "cdeject" command to eject a cd? See the man page on how to use it.

Save for this (obvious) solution there might be several problems which could prevent a CD drive to eject its content:

1. CD is still mounted
If the filesystem on the medium is still mounted the drive won't eject it. Umount it first (man umount), then eject it.

2. Unable to umount
In case you already tried 1. and didn't succeed in umounting it (probably with a "device busy" error): search for processes still accessing the filesystem and kill them. Also often seen: if your current path is somewhere on the CD-ROM drive your own login shell is the process "accessing" the filesystem - do a "cd /somewhere/else" to remedy that, tehn umount again.

3. Hardware broken
Sometimes (very rarely, but it happens) the drives hardware is simply broken (or the drive been cut off from power) and it won't eject the medium therefore. Unbend a paper-clip (or use some similar device) and push into the tiny hole in front of the drive. This will unlock the spring inside and eject the drawer.

I hope this helps.

rmumount

rmmount(1)							   User Commands							rmmount(1)

NAME

       rmmount, rmumount - mounts and unmounts removable media

SYNOPSIS

       rmmount	[-u] [-o options] [nickname | device] [mount_point]

       rmmount	[-d] [-l]

       rmumount  [nickname | mount_point | device]

       rmumount  [-d] [-l]

DESCRIPTION

       The  rmmount  and rmumount utilities mount and unmount removable or hot-pluggable volumes. The optional argument can identify the volume by
       its volume label, mount point or block device path.

       rmmount can also take additional mount options if the user has sufficient privileges to override the default mount options.

       Unmounting removable media does not result in its ejection. Use eject(1) to optionally unmount and eject the media.

OPTIONS

       The following options are supported for rmmount and rmumount:

       -d    Display the device path of the default device. This device is used if no arguments are supplied.

       -l    Display the paths and nicknames of mountable devices.

       The following options are supported for rmmount only:

       -o options    Display mount options. This option can only be used by users that have privileges to override the system default options.

       -u	     Unmounts the volume as opposed to mounting it.

OPERANDS

       The following operands are supported:

       device	      Specifies which device to mount or unmount, by the name it appears in the  directory /dev.

       mount_point    Specifies which device to mount or unmount, by the name it appears in the  directory /dev.

       nickname       Specifies which device to mount or unmount, by its nickname as known to  this command.
