Thank you for your response!
I was quite sure that the IDs were OK. And they were. Beautifully assigned 0 and 1 for ultrasatan and 2 for the scsi controller. Three days of trying, asking and searching the net for possible solutions.
Problem solved! And it was no dip switches, no driver, no partition tool, nothing like this...
As a last point of defense I changed tha acsi cable for the ultrasatan (I have bought two like these from Lotharek) and my cable is this one: http://www.lotharek.pl/product.php?pid=163
And... voila! Problem solved! I checked the first cable and I found some points of short circuits which are not present at the "good" cable after double checking.
Too many hours missed because of something like this...
Thank you all who may tried to think of something to help!
