ATATool - Windows ATA Disk Info and HPA/DCO Utility

Data Synergy ATATool Software Download Download ATATool


Overview

Data Synergy ATATool can be used to display and modify ATA disk information from a Microsoft Windows environment. We believe this is a unique capability for a freely available tool. The principle use of ATATool is to check/modify the ATA 'Host Protected Area (HPA)' and 'Device Configuration Overlay (DCO)' features.

Current features include:

  • List attached ATA devices (both legacy PATA and SATA)
  • Display device information including model/serial number, HPA and DCO status
  • Modify and reset HPA device status (SETMAX command)
  • Force Windows device re-detect following HPA status change
  • Runs inside a Windows environment (including Windows PE)

ATATool has the following requirements:
  • Windows XP SP2 or later (32-bit or 64-bit)
  • Administrator rights (elevated on Windows Vista and later)


Syntax

ATATool is command-line tool. It is supplied as a single EXE file and requires no external dependencies to function.

The command-line syntax is:


  ATATOOL action [options] [device]

Where action may be:

  /LIST - List all detected ATA devices (default)
  /INFO - Display summary ATA information for device
  /DETAIL - Display detailed ATA information for device
  /SETMAX:sectors[MB][GB] - Set maximum number of sectors or capacity
  /RESETMAX - Restore default device maximum capacity

Valid options:

  /NOREDETECT - Disable device re-detection for /SETMAX and /RESETMAX
  This option should be used with extreme caution as
  system may be unstable after reducing drive size

  /NONVOLATILE - /SETMAX and /RESETMAX changes are permanent
  Default is for changes to be discarded on power-off

Numeric values may be decimal or hexadecimal. Prefix hexadecimal with '0x'

Examples:

  ATATOOL /LIST
  ATATOOL /INFO \\.\PhysicalDrive3
  ATATOOL /DETAIL \\.\PhysicalDrive3
  ATATOOL /SETMAX:1000MB \\.\PhysicalDrive5
  ATATOOL /SETMAX:0x123456 \\.\PhysicalDrive4
  ATATOOL /RESETMAX /NONVOLATILE \\.\PhysicalDrive6
