Try adding a sleep to the changer script. Sometimes the tape drive is still settling when the write is attempted. > 23-Aug 21:38 rosalind-sd: fantom-dataOut.2007-08-22_23.10.12 Error: Error > writing final EOF to tape.

Multi-volume backups has and still is a vital feature of Bacula. See http://www.bacula.org/rel-manual/Current_State_Bacula.html: "Multi-volume saves. When a Volume is full, Bacula automatically requests the next Volume and continues the backup." Granted, it could be worded better... :) Where did you see otherwise?
