Hello,
Here's a device that is not supported yet on smartctl.
This is a multidisk device (2x128GB) to be configured with RAID0 (don't know if this is relevant), so on the same device there's also /dev/sdb with the exact same characteristics.
This drive can be found on Sony vaio SVS13A2X9ES for instance.
Best regards,
Pedro Oliveira
