8 new multiplayer maps, 2 new zombie levels, 1 epic experience! Maps: 'Hangar 18,' located in a highly classified military base where you will fight through experimental weapons labs, the SR-71 test hangar, and a mysterious autopsy room. Apple fans shouldn't get too smug about this because the firewall which shipped with Mac OS X Tiger is just as bad. Jay Beale discovered that even if you enable the “ Block UDP Traffic ” box in the firewall GUI, packets from port 67 (DHCP) and 5,353 (Zeroconf) pass right through.

I wonder if just using the kext unload command in the terminal would do it. ?? Hmm. interesting hint, thanks, this could also be good to secure your computer in lab setups.

Maybe I'm just being Mr. Obvious here, but wouldn't it be a heck of a lot easier to shut the machine down, open it up, and disconnect the ATA cable from the drive? Beats messing around with the OS.

How obvious, how could he have missed that taking apart an iBook or PowerBook is so much simpler than dragging and dropping a file into a folder.

Oh wait... 'and I didn't want to take apart the laptop and disconnect it'. Thank you Captain Obvious.

That's a powerbook,that's not use to disconnect the CABLE
thx for the author's tips
similar problem ever come to me,
but i didn't solve it,
now 3q for your guide

It Did not work for my MacBook Pro, any more Ideas?

Great hint. I tried it just to save battery on my Macbook since I never use the optical drive. But of course, now I need to use the optical drive and I'm having a heck of a time enabling it again. I moved the IODVDStorageFamily.kext back into the proper Extensions folder. Then I did:

sudo chown -R root:wheel IODVDStorageFamily.kext
 sudo chmod -R 755 root:wheel IODVDStorageFamily.kext
 sudo kextload IODVDStorageFamily.kext

Then I rebooted, and my system still can't see the optical drive. I think I need to somehow load the kext before login every time?

Nevermind, I found the solution. I simply had to plug a flash drive in and the optical drive was immediately recognized.

Just found out how to do this tweak by a more 'cleaner' manner : you just need to unload all the kext dependencies of IOCDStorageFamily, then unload IODVDStorageFamily itself :

 sudo kextunload IOSCSIArchitectureModelFamily.kext/Contents/PlugIns/IOSCSIMultimediaCommandsDevice.kext 
 sudo kextunload IOBDStorageFamily.kext 
 sudo kextunload IODVDStorageFamily.kext 
 sudo kextunload IOCDStorageFamily.kext

You can actually see all the dependancies by just looking at the command 'kextstat'.

G4 Titanium PB 1Ghz DVI Superdrive. Superdrive failed, eating my hardware test disk. I opened it up and took the disk out. Upon boot, the newly-empty Superdrive started cycling endlessly, annoyingly. Looked online, saw this post. Tried deleting IODVDStorageFamily.kext to no avail; upon restart, drive kept up the annoying cycling. Dragged and dropped IODVDStorageFamily.kext back into System > Library> Extensions. Upon restart, my external Firewire DVD drive is no longer recognized; upon opening DVD Player, I get an error message that IODVDStorageFamily.kext was installed improperly, and I should contact the vendor. Also, no DVD drive recognized.
Oh, boy. So, my Superdrive is cycling endlessly, and I'd like to stop that. I'm fine with opening the PB up and pulling a plug. Which one? Can I remove the Superdrive entirely? I'm assuming not, as the modem and inverter mount on it, but how can I disable it or stop it from spazzing out?
Worse, I cannot now play a DVD from my (recently) working FW DVD drive.
A little help, please! And thanks in advance...

Okay, I went back in and unplugged the Superdrive, so that's that. And now when I insert a DVD in the FW drive, it shows up in System Profiler, DVD appears on the desktop with the right name... But when I try to play it with DVD player, I get 'There was an initialization error. A valid DVD drive could not be found. [-70012]. Help!
Ironically enough, I appear to have disabled my optical drive, all right...

So DVD Player will not run if the Superdrive is unplugged, despite the fact that you can read the DVD from a Firewire external and open it. So it's a DVD Player problem, at this point. My 'Super' drive is physically broken and cycling really annoyingly, so I'd like to unplug it, but can't watch DVD's in DVD Player like that. Maybe another player? Otherwise, issues are solved, sort of.

I tried this, but when I wanted to un-do it I just moved the files back (I did the CD and the DVD one). But now it just comes up with an error:
System extension cannot be used
The system extension '/System/Library/Extensions/IOCDStorageFamily.kext' was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update.
Is there something I can do?

In reply to my previous comment, I got my cd drive working again by loading Disk Utility, choosing my hard drive and selecting 'Repair permissions.' It popped up one more time saying it was still not working, but then I restarted and it is all working great ;).
P.S. In the original disabling, you do have to restart before anything really notices that the drive is gone.
