All I can say is that now is working, other things changed with the new 
drives: 1.5Gbps instead of 3Gbps, also new drives don't use NCQ (I'm 
reattaching  a full dmesg).
Also I've found this firmware upgrade 
(http://www.samsung.com/Products/HardDiskDrive/support/faqs/faqs_20060414_0000246673.htm) 
for the old drives, but couldn't confirm if it should be applied because 
the server is in Brazil and I live in Argentina. Won't be there until 
April to test.

Thanks.
Pablo.
