I have tried the bls with the archive device.
The file read OK and it displayed the label on the tape. I 

When I try the same command on the actual tape, the tape does list.

Output follows :

----------------------------

The tape then scans and tells me blocks and jobs.

So, they tape is reading with bls as expected.

Will try the strace next.

Any thoughts in the output I have posted?

Stephen.

You could try to find out exactly what the SD process has read from the tape, 
e.g. using "strace -f -s 1024 ..." or gdb breakpoints.

You could add a file storage device with Archive Device = /tmp, dd the first 
block to a file in /tmp and then run "bls -d 200 /tmp/filename" to see what 
that says about the label (expect an error about "Wrong Volume mounted on 
device").
