This download creates a self-booting DOS diskette to run the DFT utility. The Drive Fitness Test (DFT) provides a quick, reliable method to test SCSI and IDE hard disk drives. The Drive Fitness Test analyze function performs read tests without overwriting customer data. (However, Drive Fitness Test is bundled with some restoration utilities that will overwrite data). Version 3.51 changes include: Increased Support for SATA Controllers: Highpoint; HPT 372A, Silicon Image; SIL 3112A and Intel CHI5. Note: Currently, the Drive Fitness Test does not support Microdrives, or Travelstar E drives.
