Jeff, That's good news. The behavior you are seeing with writes working only beyond the VOL1/HDR1/HDR2 label is likely due to the 9840C volser std label protection feature being enabled in the drive setup.

My tape operator has now gone home for the weekend, so further experimentation will have to keep until Monday. My plan is to try to repeat the above but with 'TAPE MODESET ( 3590B' - just to see what happens. Also, hopefully, we'll be able to get firmware levels checked later in the week. Teatime methinks! Have a good weekend folks. Jeff
