Fujitsu MHY2160BS, MHY2200BS, MHY2120BS, MHY2040BS, MHY2080BS manual Error correction and retry by ECC

Device Overview

(4) Error correction and retry by ECC

If a recoverable error occurs, the disk drive itself attempts error recovery. The ECC has improved buffer error correction for correctable data errors.

(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.
