When the TB bit is set in the Read-Write Error
Recovery mode page section 6.4.7 of sbc3r25.pdf
seems to imply that the good logical blocks
read prior to the unrecovered error will be
placed in the data-in buffer.
The TB bit only applies to the lowest numbered
LBA with an unrecovered error that is being read.
It seems counter intuitive to place that logical
block in the data-in buffer and not the good blocks
that precede it.
But I can't see the words that imply that the good
logical blocks prior to the unrecovered error will
be placed in the data-in buffer when the TB bit is
clear. Is this guaranteed?
