Keep taking the tablets. > Statistics reaches up and bites you on MTBF too, I had a system a while back with 1500 or so disks, A whopping MTBF of 1,000,000 hours or something like that, but when you sat down and figured it out, we could project a failure of about 2 disks a month, after the first few months, that number was almost exact, and we kept an appropriate number of spares on hand. Don't let the enormous amount of zeroes fool you into complacency with regard to MTBF. Sam sending to informix-list
