The SBC-2 specification of READ CAPACITY(10) has PMI and LOGICAL BLOCK
ADDRESS fields in the CDB; in SBC-3 these fields are simply listed as
obsolete. However, SBC-2 also has the language
If the PMI bit is set to zero and the LOGICAL BLOCK ADDRESS field
is not set to zero, the device server shall terminate the command
with CHECK CONDITION status with the sense key set to ILLEGAL
REQUEST and the additional sense code set to INVALID FIELD IN CDB.
and in fact at least the Windows SCSI compliance test checks this
behavior. Since no one following SBC-3 is going to set these fields,
we might as well include the check from SBC-2 and pass this test.
