I am using 14.04 on HP630 Laptop for around 2 months now. From the beginning I have noticed that I get a kind of clicking noise from cd/dvd rom drive every 15 to 30 seconds even though the drive is empty.

I am sure the OS is sniffing the drive for any cd or dvd. Though the noise is very mild I can hear it every now and then.

Now how do I stop it and resolve the issue. I am sure every time it searches the drive the pivot motor rotates and the lens moves up and down. By this the physical wear and tear of the drive will be faster and the life comes down considerably, added to increased power consumption of the system.

Kindly help me.

I have copied this bunch of code from one funny video clip about How does a programmer swing his baby. The code is following:

#!/bin/bash

while [ l=l ]
do
   #eject cdrom
   eject    
   #pull cdrom track back in
   eject -t
done

But it doesn't work for me, when I run it with the command sh baby_rocker.sh it performs the code and outputs the following message eject: unable to find or open device for: "cdrom" even though I have CD-ROM device on my computer.

How can I make it to work?

That's about it. Whenever I press the eject button on my cd player, nothing happens. CD player is not the cause of the problem because this never happens to me under Windows. Any suggestions?

In addition, running the eject command from a terminal also does nothing.

More information : I am running ubuntu 10.04 64 bits, have previously read a CD (like 2 hours ago), which I ejected using nautilus because I couldn't eject it using the same hardware button.

Here is the output of the command 'eject -v' :

eject: using default device `cdrom'
eject: device name is `cdrom'
eject: expanded name is `/dev/cdrom'
eject: `/dev/cdrom' is a link to `/dev/sr0'
eject: `/dev/sr0' is not mounted
eject: `/dev/sr0' is not a mount point
eject: `/dev/sr0' is not a multipartition device
eject: trying to eject `/dev/sr0' using CD-ROM eject command
eject: CD-ROM eject command failed
eject: trying to eject `/dev/sr0' using SCSI commands
eject: SCSI eject succeeded

UPDATE: Ok I would like to add that I am unable to reproduce this bug, as I upgraded to Ubuntu 10.10 using said CD, and behavior seems ok now. It was probably the upgrade to a more recent kernel that did the trick. Thanks everyone!
