So the question is, how many devices get the protect bit in the std
inquiry
incorrect?
If that is mostly correct, how about std inquiry (SPC>2), protect bit,
and then
VPD page 0x86 (or alternatively then do the READ CAPACITY, P_TYPE instead of
page 0x86)?
After all, the set of valid read/write opcodes is limited by the
protection
mode format, yes?
