The wear-out causes the "racket," which gets louder and louder until one day the disk dies. Fortunately, they are giving their own warning, leaving you plenty of time to back things up and get the disk replaced. [plenty of time= ~ 2 - 3 months, but the noise will drive you nuts before then!] We have 11 Vaxstation 3100s, each with 2 rz23 disks. We replace between one to two per month, which is quite bearable. Dec is always reasonable and prompt about replacing the disks as needed; our downtime is minimal. They are, apparently, very very aware of the problem. ----------------------------------- Esther C.
