Hello Len, thenks for your answer, i need a clarification on wheter it could be a software or a hardware problem, fortunatelly i have an exact system, so what i am going to do is to swap the four drives on the first system to the second system, and with more time i will make the required tests.
p.d. the machine is debian 4.0 amd64 system.
