Fernando, a bit off-topic, but are you aware of any incompatibilities between the Intel ICH10R controller and the Samsung estool drive diagnose tool? All my four Samsung HD642JJ drives give AJ29 "RAM error" messages when testing them with estool. I bought two new drives this week (because I need some drives during the long RMA process) and these new drives give those AJ29 errors as well! Out of curiosity I connected one of them to the JMicron 363 controller instead of the Intel ICH10R and the AJ29 error was gone... (some of the old drives really need to be RMA'd because they also give AJ24 "Bad sector" messages and one of them doesn't even boot anymore)
