Check sum

Two’s complement of the lower byte, obtained by adding 511-byte data one byte at a time from the beginning.

Insurance failure threshold

The limit of a varying attribute value. The host compares the attribute values with the thresholds to identify a failure.

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.
