Hi Allison,
Humm... the NEC databook that I have makes no mention of a "READ DIAGNSTIC" command
is this an undocumented feature or later version enhancement? If I can read "bad sectors",
even with errors, I can add another Sector Data Block flag byte value which means "data
but with errors".
Can you give me details or point me at a reference which documents this and any other
features not in the NEC data sheet?
Regards,
Dave
