Thanks guys for the help and explanation.

Finally, the driver may not have been the problem. At first, I plugged the HD to my II (original) that's where I detected it could not boot the HD. But it was the the IIsi, where I knew it was booting before. So on the IIsi I destroyed all partitions, and intall OS again, then it booted correctly.

Maybe just the way I did it on the II that generated a problem, but I can't be sure. Sure that I was simply copying the system folder, not reinstalling to it, that may also add to my problems.

Thanks again.
