• detects USB devices via USB ASPI driver only
• detects SCSI hard drives via INT13h or ASPI drivers
• other SCSI devices are detected via ASPI drivers only (must be loaded before);
• with ASPI drivers you will get more information about SCSI devices
• test and repair device for bad sectors
• many different test-functions for hard drives
• resize hard drives which supports SET MAX ADDRESS/EXT
• (supports 28/48-bits LBA addressing modes)
• drive lock detection via security feature (Security Menu)
• S.M.A.R.T. functions for ATA/SATA and SCSI drives only
