Picking the WRITE BUFFER route would require them to support N operating systems and M controllers, it is much simpler for the vendor to support a ``stuff this tape in your drive and magic will happen''. It works no matter what OS your using, and no matter what controller. Archive/Conner does this for the Python DAT drive series as well. -- Rod Grimes rgrimes@gndrsh.aac.dev.com Accurate Automation Company Reliable computers for FreeBSD
