OK. I'll try to check for this but I am not sure if there's really anything I can do about this, since this machine is on university campus using university electrical installation. The machine is already on UPS (with proper shutdown in the event of electrical outage, etc). > - controller (in this case, motherboard) failure: sometimes is not the > drive that fails, but the controller, rendering the disks useless. I am suspecting this too. But something I was not sure, could a bad controller render a drive to be physically damaged / bad as well ? My controller is on PCI card, any way to determine if they are bad ? or is the motherboard ? The system drive that plugs directly to the motherboard (not part of the RAID array) has never had any problem. Thank you for your respond. RDB -- Reuben D. Budiardja Dept.
