Hi. Cannot insert blank CD disc's into my computer. It just spit them right out. I've tried repairing permissions, rebooting AND Macjanitor. After I use Macjanitor, I can insert the disc, start the burning process and then get an error message. (I don't know about DVD's. I don't need to burn a DVD right now, and it would be a little bit expensive to find out that I can't use them.) I'm seeing a lot of other cases of similar activity on the apple powerbook board, in a very recent timescale... somebody mentioned the recent security update. So... has apple wrecked my Powerbook? And is there anything I can do about it?
