Tim,
This is _not_ an error. If the CK_COND bit is set in the SCSI
ATA PASS-THROUGH (12 or 16 byte) cdb and the ATA command
succeeds then what is shown above is correct.

The whole point is to get the ATA registers after the command
is complete. The register values are placed in a ATA (status)
return descriptor encapsulated in sense data with that sense key
and those additional sense codes. The ATA return descriptor
starts with the "09" value in the sense buffer shown above.

smartmontools needs to set CK_COND on some ATA commands (e.g.
to get the SMART status) because the result can only be found
in the ATA registers after completion.

Now it is annoying, distracting and wasteful to log the sense
data in this particular situation. Perhaps the SCSI mid level
error reporting should filter out that particular combination:
   Sense key: RECOVERED ERROR
   Additional sense: ATA PASS THROUGH INFORMATION AVAILABLE (0x0,0x1d)
