Please always include the first line in sample outputs as it reports the 
version of smartmontools and OS.

Which SATA controller and driver is used?

SAT is auto detected if
- the OS reports the device protocol as SCSI, and
- the SCSI INQUIRY result conforms to SAT (VENDOR: "ATA     ").

For further diagnostics, please provide the output of the following 
commands as plain/text attachments:

smartctl -r ioctl,2 -i /dev/sda
smartctl -r ioctl,2 -d scsi -i /dev/sda
smartctl -r ioctl,2 -d sat -i /dev/sda
