Not sure that the drive should ever knowingly fail INQUIRY and REPORT LUNS.
That is to allow a discovery process to occur. In the INQUIRY response the
peripheral qualifier should be 000b by my reading.
Go look at sbc4r15.pdf, specifically clause 4.11.2 to see all the commands that
should be responded to during a SANITIZE (there are
9 of them).
