It's hard to say what's wrong with your drive, although you do have one of those HP/Philips WORM drives that's known to be a bit screwy. If you boot without media in it, it'll probably take a long time for the probe message to show up, since the drive takes forever to return a read capacity command when it has no media. Just because the CD in question works fine with other OSes doesn't mean that FreeBSD's cd9660 code can handle it. If the test unit ready you issued above was done when there was media in the drive (i.e. the CD in question), then you've likely got a hardware problem of some sort. That's because the drive is telling you that it doesn't have any media. There's nothing the OS can do to affect that behavior, unless it's the result of some bizarre firmware bug that requires commands to be sent in some non-standard order. I doubt that's the case, though, since other people have identical drives that function just fine. If your drive is reporting medium not present when a CD is in the drive, there's probably something wrong with it. If it does the same with every CD you stick in it, that just makes the results more conclusive.
