In an amazing display of technical merit, i just took apart and put back together my CD drive, and now it works again (and i found a piece of it that i had presumed as gone for over a year now, which presumably was blocking the track of the tray). In an equally amazing display of early morning numbness, i missed the bit on my Recording Exam where it said “and define the terms” on a question where i knew the terms better than i know my own foot size. Damned feet.
