I'm really not sure... I know that btape works correctly; at least it did so everytime I used it. LTO tapes, too, can be used without problems by Bacula, and btape testing them works for me and many others, too. Finally, I'm quite sure that Bacula is run on Spektralogic hardware somewhere out there. Currently, I can only recommend to ensure you've got the latest firmware for HBA and tape device, a proven driver and kernel on your system, and run a current version of btape. If the problem persists (which I assume) you should file a bug report at bugs.bacula.org and perhaps also contact the developers of the SCSI driver you're running. Apart from that I can only wish good luck...
