Depends on how much equipment you extend your opinion ;-) No, i do not really want to argue too much. It was just a stray idea. And when there would be a prebuilt, working solution - one that probably takes your arguments into account and "heats up" the disk(s), before it fully uses it - it would not be a bad thing. And when every bacula user in the whole world would use it... ;-) (mk) -- Matthias Kurz; Fuldastr. 3; D-28199 Bremen; VOICE +49 421 53 600 47 >> Im prämotorischen Cortex kann jeder ein Held sein.
