I think the magic word -- or acronym -- there, may be "IDE". IDE performance *sucks*, especially if you have more than one device on a channel. What are the spool disk and the VS80 connected to? Can you get them both onto their own IDE channels with no other device sharing that channel? -- Phil Stracchino [EMAIL PROTECTED] Renaissance Man, Unix generalist, Perl hacker Mobile: 603-216-7037 Landline: 603-886-3518 ------------------------------------------------------- SF.Net email is Sponsored by the Better Software Conference & EXPO September 19-22, 2005 * San Francisco, CA * Development Lifecycle Practices Agile & Plan-Driven Development * Managing Projects & Teams * Testing & QA Security * Process Improvement & Measurement * http://www.sqe.com/bsce5sf _______________________________________________ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
