Don't you guys You want to hide SCSI errors behind the verbose flag? This is not the right way to go at all. Yes, you could argue that in the case of removables, different handling of certain errors would cut down on console traffic, but as a general rule, if there's something unhappy going on on the SCSI bus I'd prefer to know about it. -- ]] Mike Smith, Software Engineer msmith@gsoft.com.au [[ ]] Genesis Software genesis@gsoft.com.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control.
