(5) Self-diagnosis
The disk drive has a diagnostic function to check operation of the controller and disk
drive. Executing a diagnostic function of the smart command invokes self-diagnosis.
(6) Write cache
When the disk drive receives a write command, the disk drive posts the command
completion at completion of transferring data to the data buffer completion of
writing to the disk media. This feature reduces the access time at writing.
