Thank you very much networkpc3000!
But I have to change problem in this topic.
I asked of new ROM for that drive because I was sure that ROM is corrupted. After starting WD utlility in PC3K there was error at Zone Allocation table (RAM section of ROM). This error was even when I boot up PCB in kernel mode, so no reading from HDA. I put on my PCB ROM given to me by networkpc3000 and I have the same problem. It cannot be PCB, because I put different ROM version on this PCB from the same MDL drive and that one is ok.
My question is: what's going on with this case or maybe I'm unlucky enough that copy from networkpc3000 is also bad?
Comparing my original ROM and the one from here - they are identical
