DVD-RW device disappear (no drives)

@R0GUEHave you checked the physical connection on your ATA bus? Something similar happened to me a while back. I disconnected the IDE cable from the device and reinserted it which rectified the problem.

Nope, in windows drive works good :

Both files are same as from previous installation where drive is working good

Nothing happened after the kernel (to voodoo_beta2) and some kext's (AppleNForceATA.kext and System.kext) was updated. Still "No Drives"

Hmm, which of this files is being used to allow to see DVD?

$ kextstat:

Current system

AppleNForceATA.kext have no difference between DVD's and system's.
IOATAFamily.kext have differenses.
DVD plugins:
AppleGenericPCATA, AppleIntelPIIXATA, AppleOnboardPCATA, IOATABlockStorage, IOATAPIProtocolTransport

Inside the IOATAFamily.kext file is located folder Contents and IOATAFamily.kext Inside this IOATAFamily.kext/Contents/Plugins: AppleGenericPCATA, AppleOnboardPCATA, IOATABlockStorage, IOATAPIProtocolTransport

System plugins:
AppleIntelPIIXATA, IOATABlockStorage, IOATAPIProtocolTransport

IOATAFamily from DVD and system (rapid share.com/files/154878603/IOATA.zip.html)

Thanks for helping!

Nope, it hasn't helped :'( Stil "no drives" and in System Info in ATA device tree just the "ATA Bus:" and blank page

DVD-drive must to be master if slave is not installed. My problem is solved, DVD-drive appeared. ^_^

hmm, it could be that your kextcache need rebuilding. Try booting with -f and see if that helps?

Have you checked the physical connection on your ATA bus? Something similar happened to me a while back. I disconnected the IDE cable from the device and reinserted it which rectified the problem.

Me too , no dvd drive after install ideneb 10.5.4 but update 10.5.5 , still missing dvd drive , weird when dvd install worked good then it gone , is there something missing from kext I tried different kext to install from osx86 tools , no go.

I think it's to do with either AppleNForceATA or IOATAFamily. You may find your old working IOATAFamily.kext was replaced in the update.

use your install DVD and boot up to the Terminal... use kextstat to find out what kernel extension is being used to allow you to see your DVD. Then copy this file to the volume of the Hard Drive you boot from and into your Extensions folder. Then fix permissions and reboot using the boot flag -f

when you are in the install DVD from boot, copy the IOATAFamily.kext to the desktop of your installed system. Also, copy the AppleNForceATA.kext file over as well as it appears to be used. I am not sure (since I haven't used Zeph's rev2 DVD) but is there a few difference between the two AppleNForceATA.kext files? I would also look inside the IOATAFamily.kext file (right click, show package contents) and navigate to Contents/Plugins to see what else is located within this file... usually there are more ATA files placed in there.

EDIT: Also see if the AppleAzaliaController.kext file is needed. These are the primary differences I am seeing.

Simply copy the DVD's IOATAFamily.kext file to your /System/Library/Extensions/ folder, then open Terminal.

sudo -s
cd /System/Library/Extensions/
chmod -R 755 * && chown -R root:wheel *
cd ..
rm -Rf /System/Library/Extensions.mkext

Now reboot with "-f" to ensure everything was reloaded.
Let me know how it works out.
