DVD drive not detected

[PreferLinux]

Anyone have any ideas why a DVD drive that works perfectly isn't detected by openSUSE 11.4 x86_64? Yesterday I downloaded the net install CD, burnt it, and used it. It worked perfectly, but the DVD drive isn't detected. dmesg gives some obscure error, and there is no device for it in /dev. It still works perfectly from within Windows or before booting to openSUSE. It was working fine in Fedora a few days ago. The drive is a LG GH22LS50 (SATA) on one of the SATA3 ports on my GA-P67A-UD3R motherboard.

Well, the obvious first step in troubleshooting would be to move the drive to one of the SATA 2 ports. It's not as if data transfer rate is a big deal with a DVD drive.

And it might help if you could actual reproduce that obscure dmesg error here. It may be less obscure to some of the geniuses who hang around this forum.

By obscure (with reference to "TEST_UNIT_READY failed"), I meant that a Google brought very few results.

I was intending to try one of the SATA2 ports, but hadn't got around to it yet. I will do so soon.

Well, I tried with the SATA2 ports, and it works fine. That is nice, but I wanted it to work on the SATA3 ports because of the chipset bug. I guess it doesn't matter, as I'll be getting a replacement within a few days.

I Googled that error message and it's a known problem with some SATA 3 ports. Anyway, glad it's now working.
