The purpose of SeaTools diagnostics is to save you time, data, and money by helping you keep healthy hard disk drives.
SeaTools for Windows tests SATA, USB, 1394, ATA (PATA/IDE) and SCSI drives, and is data safe.
SeaTools for DOS
SeaTools for DOS tests SATA or ATA drives from a bootable CD-ROM or floppy. It can test a SATA (Serial ATA) or older ATA (PATA/IDE) interface hard drive. Because the software boots to its own operating system you can test your drive regardless of the OS installed on it. You can even test a new or completely blank drive. In addition, this version offers limited repair and data erasure.
