Can't duplicate any disk

I got your board back.  Duey was indeed bad.  I replaced it and made a change also to the media integrity test.  It turns out that the random pulse width was not working, so a test generated by a good SCP board would have good data when the write was not working (like in your case).  I don't know if the SCP board left here with Duey bad, or it was damaged by your drive or cable.  The new media integrity test will definitely now make sure the write gate is always working before leaving here.
