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.
