It means they aren't changeable - changeable fields will be all 1 bits, non-changeable all zero bits. Maybe there are some other steps you have to take before the block size become changeable, such as a jumper or a setting in a different mode page. I'm afraid nothing jumps out at me looking through the direct access mode pages, though. -- Peter Dufault Real-Time Machine Control and Simulation HD Associates, Inc.
