It have 1.06 firmware (flashed yesterday, before I used 1.04) and it's alone as a secondary master.

Have you ruled out a posibility of defective unit? Can you try it in other, preferably Windows, box? Can you try with cdrecord-ProDVD? What does "atacontrol mode X" reports? (X is 0 or 1 depending on the channel you have unit connected to). -- Pav Lucistnik <pav@oook.cz> <pav@FreeBSD.org> In fact, the GAH is a very powerful and secretive organization whose single weakness is its lack of existance. - rec.games.roguelike.angband
