HDAT2 6.5 (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. 

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


fully implemented commands: SET MAX, SET SECURITY, Device Configuration Overlay (DCO)
device access with interrupt 13h, direct via ATA ports, with ASPI drivers
detects ATA/ATAPI/SATA devices with on-board and add-on controllers
detects devices on AHCI/RAID controllers (just only on ports 0-3) 
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 (so far version 4.5.3 only)
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
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)
Known limitations:

change SATA controller in BIOS from AHCI to IDE/ATA/legacy mode devices SATA/AHCI/RAID detect on ports 0-3 only
