METHOD FOR DETECTING PROBLEM CELLS OF SATA SSD AND SATA SSD HAVING SELF-DETECTING FUNCTION LOOKING FOR PROBLEM CELLS

摘要

A method for detecting problem cells of a SATA SSD and a SATA SSD having self-detecting function looking for problem cells are disclosed. The method includes the steps of: providing a detecting program used to detect aged and died cells in a SATA SSD; writing the detecting program to a MCU (Micro Control Unit) in the SATA SSD; pulling high electric potential of a communicating pin of a SATA connector of the SATA SSD to initiate the detecting program; collecting location data of aged and died cells in the SATA SSD by the detecting program; and storing the location data in a storage area in the SSD. The present invention utilizes the DAS/DSS pin as a channel to initiate detecting program. It has advantages of using current interface of SSD, no effort on taking apart hardware and automatically running the detecting program without human control.
