Write only? Sure, that's been around since at least 1972! http://www.ganssle.com/misc/wom1.jpg http://www.ganssle.com/misc/wom2.jpg </smartassmode> :) If you mean READ only, some of Sandisk's products (not their normal consumer grade Compact Flash disks) have a read only mode. Some of which even have a mode where you can blow a fuse inside the chip with a special instruction, and make it read-only forever. Someone else made a solid state flash based IDE compatible drive, too, that had an option for "write once" per sector (yet could be all blanked using another special command). I know they wrote a module for OS9 to support it using its native filesystem (most FS's don't like being unable to write to whatever they want, whenever they want). It may have been Atmel. -- Kevin
