Thanks for your answers.
As far as I can deduct from the answers up to now... SATA burners are not as reliable as IDE ones.
I suspect there is a bit of "resistance to change" in the answers. I also have this resistance, in part for the prices of the new artifacts or pieces and partially because I have seen many cases of faulty new artifacts and after some time the defects were corrected. "Second generation" artifacts are allways better than the very first generation ones.
Even worst, in some cases there were no second generation (Rambus memories, for example). I can acquire PC100 memories from several sources but it is very difficult to obtain Rambus memory today.
As I said in the first, I expect this thread will be useful for people with same questions.
