CD ROM not opening

OK, I have had this problem before when I started to use linux and I don't quite remember how to fix it. Now it came back. The problem is the following, the command eject will not work because it cannot find the device 'cdrom', in fact

$ls /dev/cd* 
ls: cannot access /dev/cd*: No such file or directory

Also it won't eject even by pushing the button of the cd drive ( on the computer ), same as klohs.
Here is some information:
I used "sudo lshw -c disk" and the only output was my hard disk. With

$ lsmod | grep cd
ide_cd_mod             24177  0 
ide_core               76991  1 ide_cd_mod
cdrom                  31410  1 ide_cd_mod
uhci_hcd               19251  0 
ehci_hcd               32232  0 
usbcore               121705  4 usbhid,uhci_hcd,ehci_hcd
dcdbas                  4388  1 dell_laptop

When I start the computer I can eject the cd just before it prompts the grub menu, so I think that the drive is working, but after it reaches the menu it does not allow me to eject it. If I go to the bios menu I cannot eject the tray either. I remember that when it happened last time I had to eject the drive with a paper clip and close the tray once Ubuntu started. Then it would be recognized and I could use the drive normally. Then if I ejected used the button on the tray it would stop working, of course this is not working anymore. I will try to boot from the cd drive ( I don't have any cd with me right now ), and I will post if it was successful. ( now I'm using Arch now  ). Is it possible that is grub's problem?
Thank you!.

Re: CD ROM not opening

What does mount (or /etc/mtab) give you? Anything mounted?

Also, try:

# eject
