Oh ... one other thing ... I have an external CD/DVD re-rewriter. When I insert an audio cd in it, it overrides the internal one which then dissapears but with no on screen unmount. If I have my desktop set where it shows audio cd icons, both will show up but both when opened will open the external drive only. If I cut it off, the internal audio will then reappear but will still be un-ejectable. This was not a problem until the last week either. I don't know what is causing either issue.
