Blank CD-ROM icon on desktop without disc in drives

Binary package hint: udev

Lucid (fully updated on April 14) shows a blank CD-ROM icon on the Desktop without any blank media in either of my two drives. If I right-click and eject the fake blank CD-ROM, my IDE-based CD-RW drive opens. The SATA-based DVD-RW/CD-RW drive does not.
