It seems that your firmware is version NA00. To my knowldege, all firmware start with A, as in A3EA or A3MA. Usually we don't even say about this first A, saying only 3EA or 3MA. Your firmware, starting with letter N, is really something "N"ew...Some of my older Hitachi Ultrastar HUA722020ALA330 2TB disks have firmware revision JKAONA00. I haven't seen this A00 revision mentioned here in this thread; and trying to upgrade to a more recent revision such as 3EA or 3MA using the DOS utility fails. Hitachi support didn't know what to do. Any ideas?
If we disregard the "N", FW A00 is newer than FW 800.
