Well, I suspect the tape is hanging the bus, from which no card can recover. Just to test this, can you try sending a bus reset with sgutils (from the debain package sg3-utils): sg_reset -b /dev/sg3 Then remove and re-add the device with echo scsi remove-single-device 1 0 6 0 > /proc/scsi/scsi echo scsi add-single-device 1 0 6 0 > /proc/scsi/scsi And see if that brings it back. If it doesn't I'm afraid the tape has the bus locked and nothing can free it. James
