Gary,
As with all Inquiry bits and fields, those three bits define what the
device is capable of doing. No amount of formatting can change what the
devices reports in those bits.

data protection format types
I have a question with regard to the discussion in SPC4r04
In clause 7.6.4 Extended INQUIRY Data VPD page, there are 3 bits discussed
GRD_CHK,
APP_CHK and
REF_CHK
They are defined as far as their meaning, but never discussed how they are
set.
Is this part of the format process, or simply the capability of the device
firmware or design?
I got a response that said go look at any protected command (i.e.
read/write, etc.), however that does not answer the question.
Are these 3 bits somehow tied to the format type (type 1, 2, or 3)
