Smart Error Log Data Format - Fujitsu MPE3XXXAE Product Manual

Error logging capability
Bit 0: Indicates that error logging function.
Bits 1 to 7: Reserved bits
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.
