[ubuntu-uk] Lock empty CD/DVD drive from command line

[Rob Beard]

Hi folks,

Not sure if anyone could help on this one...

My youngest daughter who is nearly 3 is in the habit of messing around 
with my PC when I'm at work.  At first she did things like hit the reset 
button or power button and now it's more of ejecting my DVD drive.

Unfortunately the last time she did this she also lent on the drive and 
physically broke the mechanism.  Now I've just got a new drive but and 
I'd rather avoid it happening again (drives are cheap, but it's an 
inconvenience having to buy a new one).

As a temporary measure I've put a disc in the drive, made sure it's 
mounted and then gone into the disc in a terminal (which when the eject 
button is pressed it says that the disc is in use).  What I'd like to do 
though is disable the eject button by software.

I did a google search and found this...

As great as it is though it doesn't seem to work (despite altering the 
code to point to /dev/scd0 rather than /dev/hdc).

So I wondered if anyone had got any other ideas on how to do this?

I'd probably forget to keep a disc mounted in the drive knowing my luck 
so it would be handy to say have a command line utility to lock the 
drive say when the screen saver is active?

(I presume it's possible to send some sort of command to the drive to do 
this?).
