A couple months ago I disabled the SuperDrive on my MacBook 4,1 because I have a DVD stuck and it wouldn't stop reading it. I did this by moving the "IODVDStorageFamily.kext" and "IOCDStorageFamily.kext" files out of the /System/Library/Extensions folder. Now I want to copy the disk image from the DVD in the drive to a USB drive and to do this I need to reenable the SuperDrive. I put the .kext files back in the Extensions folder and rebooted, but nothing happens. I know that the drive reads the disk because it shows up when I boot into my Linux partition. Is there something I'm missing?
