SMART Self-Test

The host computer can issue the SMART Execute Off-line Immediate sub-command (Features field = D4h) and cause the device to execute a self-test. When the self-test is completed, the device saves the SMART self-test log to the disk medium.

The host computer can issue the SMART Read Log Sector sub-command (Features field = D5h, Sector Number field = 06h, Sector Count field = 01h) and can read the SMART self-test log.
