Your expert sounds like he is full of B.S. when he says to look at your motherboard as a possible cause. Plain and simple fact that an electronic device can not cause a physical failure of a disk drive. Vibration, shock, or another physical thing happened here if 2 drives in the same chassis died at the same time with the same ``heads hit the platter'' failure mode, no doubt about it in my mind at all. -- Rod Grimes rgrimes@gndrsh.aac.dev.com Accurate Automation, Inc.
