Descriptor sense format, sense_key=ABORTED_COMMAND
with no additional sense code (0x0,0x0).

It has also added an ATA Return descriptor which
purports to be the ATA registers after the command
is processed. That starts at the 0x09 byte. See
sat2r09.pdf table 114 to decode that.
Since it is an aborted command I would not take
that too seriously.

It is incorrect to have an ATA Return descriptor
with asc,ascq=0x0,0x0 .
