Many years ago I had friends in old DEC building in Maynard, MA. They had story of periodic head crashes on monster disk drives with vertically spinning platters. They realized cause: trucks backing into loading dock hitting and shaking the building -- since platters were oriented perpendicular to truck motion. Solution: turn drives 90 degrees to align platters with truck motion. At worst, I/O errors but no head crashes (I guess heads flew much higher than on today's devices). I'll ask veterans I know of that time/place to confirm...

The technician installed and configured the array, but for some reasons, it was not immediately used by the client. few days later, the client tried to connect to the array and it was down. it was repeatedly don everyday afterwards. investigation showed that the the people who cleans the computer room unplugged the power for the vacuum cleaner... The array was using a standard power plug. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
