The ROM serial is not lost. I can still retrieve it on those devices after the normal reset that follows the Fat/Ex.
My gut feeling is that it is related to the NAND flash. Maybe some funny "wearing off" of memory cells that produces read/write errors? It seems also, that devices that just had a hard-reset do not produce this error or maybe they produce it just later. -- For information on using the ACCESS Developer Forums, or to unsubscribe, please see http://www.access-company.com/developers/forums/
