SMART error logging

If an unrecoverable error is detected during execution of a command received by the device from the host computer, the device saves the SMART error log on the disk medium.

The host computer can issue the SMART Read Log Sector sub-command (FR register = D5h, SN register = 01h) and read the SMART error log.
