So that might be the hard or soft part of IDE layer failing the system, or a PCI problem for example? Just in case, motherboard is Supermicro X5DPE-G2: e7501 chipset, Dual Xeon-533. Rather old now, way cool back when it was bought ;) But, as anything new, it could be manufactured bad. Maybe now there are some well-known problems with the tech?
