HDAT2

Overview of HDAT2 (ALL-IN-ONE BOOT version)

HDAT2 is program for test or diagnostics of ATA/ATAPI/SATA, SSD and SCSI/USB devices. It will not execute in a DOS session under Windows. You should make a DOS boot floppy disk or CD/DVD and boot your system for it and execute this program from that floppy disk or CD-ROM.

Features of HDAT2

• Fully implemented commands: SET MAX, SET SECURITY, Device Configuration Overlay (DCO) and other
• Device access with interrupt 13h, direct via ATA/AHCI ports, with ASPI drivers
• Detects ATA/ATAPI/SATA/NVMe devices with on-board and add-on controllers
• Detects devices on AHCI and some RAID controllers
• Detects USB devices via USB ASPI driver or BIOS (if supported)
• Detects SCSI hard drives via BIOS interrupt 13h 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 ATA/SATA hard drives which supports SET MAX ADDRESS/EXT
• (supports 28/48-bits LBA addressing modes)
• Resize and change sector size of SCSI disks
• Drive lock detection via security feature (Security Menu)
• S.M.A.R.T. functions for ATA/SATA,SCSI and NVMe drives only
• Information about devices (ATA/ATAPI, BIOS interrupt 13h, ASPI, EDD)
• Sector viewer for devices (also for USB, ZIP, CD-data discs) to access ATA/SATA CD/DVD drive you don't need any driver or MSCDEX
• Enable/disable some features for direct-access devices
• Device Configuration Overlay (DCO) feature set
• (you can restore a full capacity or allow/disallow some feature sets of hard drive)
• SATA/NVMe: converts between 512e logical sector size and 4Kn, if supported.

HDAT2 program has 2 levels:

Device testing

• Main function is testing and repair (to regenerate) bad sectors for detected devices
• You get much information about detected devices

File system testing

• R- read/find/check items (MBR, boot, directories, etc.) of file system FAT12/16/32
• Check/remove (regenerates) bad sectors records, flags in FAT table.

Program notice:

• HDAT2 is running in DOS protected mode and is compiled with a free 32-bits Free Pascal compiler v3.2.0.
• Both program's level ('drive' and 'file') are integrated into one program.

Minimal configuration:

• CPU 386/486 with co-processor or higher
• RAM 1 MB or more
• DOS boot system.
