So I put in a DVD-RW into my iBook, with the intent to burn something to it. Got an error, and the computer ejected the disk. I wanted to try again, but alas. I pushed the disk back in before I clicked 'okay' on the error window that popped up. Then the cd drive starting making a lot of unfortunate noise. Now the disk won't show up anywhere. Not on my desktop, nor in any finder windows, or in the disk utility. It also will not eject when I push the eject button that's on my keyboard. Restarting doesn't make it show up, either. Long beyond wishing to burn anything, I just want the evil thing out of my computer. Is that possible? Please say it is and how to I do it? I honestly always feared something like this would happen.
