It looks like your drive is returning an error when there is no CD in the drive, which is normal. What is not normal is that it isn't providing sense information to tell us what that error is. So this didn't happen before? Have you done anything to the drive? (like upgrade the firmware?) When did you last build a new kernel before this happened? I suppose this started happening when you last built a kernel/world? Do you have any other controllers you could put the drive on to see if it is a controller/driver issue? Try this, without a CD in the drive: camcontrol cmd cd0 -v -c "25 0 0 0 0 0 0 0 0 0" -i 8 "i4 i4" Then try it with a CD in the drive.
