Samsung Hard Disk Drive Diagnostic Utility ~ ES-Tool
ES-Tool can test a drive solely manufactured by Samsung. And it is a DOS based utility. So you need to have bootable 1.44-MB diskette or CD-ROM. Floppy drive is long gone by now. I still have issue to create a bootable USB Pen Drive. So the only way is use CD-ROM.
