I've rebooted the machine a few times. I'll try again, after i set the cables again. One question; i don't have to run amtapetype every time i do this do i? For instance, say the speed problems are resolved, will amdump pick up on this automatically or does it stick to the tape speed given in amtapetype absolutely? +---------------------------------------------------------------------- |This was sent by [email protected] via Backup Central. |Forward SPAM to [email protected]. +----------------------------------------------------------------------
