Thanks for keeping us updated on this issue. I'm going to refer you to the hal people for help since this seems to be a polling issue maybe with hald-addon-storage. I've seen them before, although not with those drives. In the meantime, try installing another drive if you can find a spare and make sure that it is the CD-ROM drive that is the issue, not the controller or any of the supporting hardware.
