The SSD might not be in the smartctl data base at all, or it might not provide correct information. On Linux I'm running the vendor's Linux software, to get smart data, that most likely is correct and to update the firmware, while the SSDs are in use. Mine are cheap Toshiba SSDs. $ sudo ocz-ssd-utility Not all vendor's support FLOSS operating systems, hence I cared for this, before I bought my SSDs.
