Charles, Thanks for looking at this. Every time I think we have a write protect solution, it doesn't pan out. :-( >More detailed explination: >Pin 30 is defined as a ground pin by the ATA specifications >(http://www.t13.org/), so conforming motherboards and controllers do >*not* have a means to toggle this pin high or low.

In other words, you need a custom motherboard/ata controller, to support WP# pin 30. >I would suggest folks wanting to make use of this new ATA flash disk >with write-enable wire a switch between pins one and two of the WP# >jumper on the disk module (perhaps using an old "turbo" switch, if >you're lucky enough to have one available on your case of choice). This is the solution I was hoping for, but it looks like the ADM on board three pin jumper is for master/slave selection not WP#. :-( -- Mike Noyes <[EMAIL PROTECTED]> http://sourceforge.net/users/mhnoyes/ http://leaf.sourceforge.net/content.php?menu=1000&page_id=4 _______________________________________________ Leaf-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/leaf-devel
