In fact of the drives returned to Samsung, a large percentage are NTF("No Trouble Found") after testing. So it is strongly recommended to test the drive if it is truly defective by a few fundamental troubleshooting of ES Tool first, to avoid user's unnecessary effort and inconvenience of replacing a good drive.
ES Tool can test a drive solely manufactured by Samsung. It is strongly recommended to back up the user's significant data in advance because ES Tool has a Write operation that can erase it. Samsung has no responsibility of lost data.
