Any user leaving his system continually powered on is placing their data and system at some risk. We regularly lose systems to lightning strikes in the area, facilities also regularly destroys systems with their constant screwing with the power. These systems would not have been damaged if they had been powered off when not in use. If you've got conditioned power and battery backup, then the vagaries of weather and power grids will not be a concern. My mainframe customers generally power their systems down, when possible, during thunderstorms. Data loss is a real threat to any mini or mainframe systems during a power loss event. A large disk drive performing the old "spiral write" during power loss is something any experienced computer technician has seen. The loss of system power supplies is not an uncommon occurence during these power-loss/power-surge sequences. -- ---------------------------------------------------------------------- HONEYWELL Third Party Computer Service -- 1(800) 525-7439 Mike Thomas, Senior Technician, Albuquerque, New Mexico honeywel@wayback.unm.edu (505) 888-5820
