Hutil (The Drive Diagnostic Utility) is made with the aim of testing a Samsung hard disk drive while it is installed inside a PC, regardless of the status of user's operating system. Hutil can test a drive solely manufactured by Samsung (supported models). It is strongly recommended to back up the user's significant data in advance because Hutil has a Write operation that can erase it.

This download is to create an ISO (CDROM). It is also available if you need to create a floppy disk.
