Bytes identified as being in error are not necessarily the bytes that need

A Command Data bit of 1 indicates that the illegal
parameter is in the CDB.
A Command Data bit of 0 indicates that the illegal
parameter is in the data sent by the initiator during the
Data-Out phase.
A Bit Pointer Valid bit of 1 indicates that the Bit Pointer
field specifies which bit of the byte designated by the
Field Pointer field is in error.
A Bit Pointer Valid bit of 0 indicates that the Bit Pointer
field is not valid.
When the Bit Pointer Valid bit is 1, the Bit Pointer field
specifies which bit of the byte designated by the Field
Pointer field is in error. When a multiple-bit field is in
error, the pointer points to the most significant byte of
the field.
The Field Pointer indicates which byte of the command
descriptor block or the parameter data was in error.
Bytes are numbered starting from 0. When a multiple-
byte field is in error, the pointer points to the most-
significant byte of the field.
