Launching the program

Tested with HDAT2 version 5.0.
  • You will get a menu where you need to select the type of HDD.
  • For a typical IDE/SATA HDD select: (1) PATA/SATA CD driver only (default)
  • If you don't know the type of HDD being used, select option (4).
  • A command prompt will be displayed.
  • You can enter your commands after
     [PATA] X:\> 
    • Type :
      To start the program .
  • Choose SATA and select the disc you want to repair. You will get information about the size and model of the HDD.
  • Note that: HDAT2 may falsely detects the SMART status as "Failing" (Red), while it is not the case when running tests with the manufacturer's tools.
    • Hit the "D" key to Detect/ Refresh HDDs.

Test and repair

  • Select "Device tests" menu.
    • Warning: WRITE tests can cause data loss.

Two choices are available:
  • Scan the hard drive without WRITE tests- Detect Bad sectors
  • Scan the hard drive with WRITE tests - Detect and fix bad sector menu

If you wish to continue with the repair :
  • Choose "Fix with VERIFY/WRITE/VERIFY".
  • HDAT2 will scan and regenerate bad sectors.
  • Once everything is repaired, run a second scan but this time using the "Detect Bad Sectors menu" without the WRITE tests.
  • If other bad sectors are detected it means that your HDD is dead (it will slowly deteriorate until it is completely out of order)!
