13 Best Free Hard Drive Testing Tools (March 2024)

SeaTools, HDDScan, and GSmartControl are my top picks

There are many free programs you can use to test your hard drive to determine what, if anything, is wrong. Below are my top choices that I've recommended to people for years.

Most apps have similar features, but some only work on specific hard drives. No matter which software you use, you may need to replace your hard drive if it fails some part of one of these tests.

Your Windows-based operating system includes tools like Windows Error Checking and the chkdsk command. Still, others, like those below, are available from hard drive manufacturers and other developers.

Seagate SeaTools

Seagate SeaTools for DOS
What We Like
  • Works from both inside and outside of Windows

  • Completely free

  • SeaTools for DOS works on any operating system

  • Windows tool lets you test a hard drive from any manufacturer

What We Don't Like
  • SeaTools for DOS can be hard to use and install

  • DOS version can deal with only 100 errors before restarting

  • DOS edition might not work well with RAID controllers

Seagate SeaTools is free hard drive testing software that comes in two forms for home users:

SeaTools Bootable and SeaTools for DOS support Seagate or Maxtor drives and run independent of your operating system on their own USB drive or CD, respectively.

SeaTools for Windows installs on your Windows system. Use it to perform basic and advanced testing of any kind of drive—internal or external—from any manufacturer.

Seagate's programs are excellent. They are used to test hard drives by professional computer services, but are easy enough for anyone to use.

The Windows version should work with Windows 11, 10, 8, 7, Vista, and XP. There's also a Linux version.

For those looking for SeaTools Desktop, SeaTools Online, or Maxtor's PowerMax software, please note that the tools above have replaced all three. Seagate now owns the Maxtor brand.

What We Like

HDDScan is a free hard drive testing program for all types of drives, no matter the manufacturer. It includes a SMART test and a surface test.

Some reasons I choose this app is because it's easy to use, is completely portable, supports almost all drive interfaces, and seems to be regularly updated.

The official system requirements state that you need to be running at least Windows XP, so it should work with Windows 11, 10, 8, 7, and Vista, including Windows Server 2003.

GSmartControl

GSmartControl
What We Like
  • Choose from three different tests

  • Works on Windows, Linux, and macOS

  • Lets you view the drive's SMART attributes

  • A portable version is available

What We Don't Like
  • Doesn't support every USB and RAID device

  • When exporting information, it includes everything, not just a specific result you want to save

GSmartControl can run various hard drive tests with detailed results and give an overall health assessment of a drive.

View and save SMART attribute values like the power cycle count, multi-zone error rate, calibration retry count, and many others.

GSmartControl runs three self-tests to find drive faults: Short Self-test takes around 2 minutes to complete and is used to detect a completely damaged hard drive, Extended Self-test takes 70 minutes to finish and examines the entire surface of a hard drive to find faults, and Conveyance Self-test is a 5-minute test that's supposed to find damages that occurred during the transporting of a drive.

This program can be downloaded for Windows as a portable program or as a regular program with a normal installer. The latest version works with Windows 11, 10, 8, 7, and Vista, but there's an outdated edition you can get for older Windows versions. It's also available for Linux and Mac operating systems, as well as included in a couple of LiveCD/LiveUSB programs.

DiskCheckup should work with most hard drives. SMART info like reading error rate, spin-up time, seek error rate, and temperature is displayed, as well as short and extended disk tests.

Details in the SMART section can be configured to send an email or display a notification when their attributes exceed the manufacturer's recommended threshold.

DiskCheckup should work fine with Windows 11, 10, 8, 7, Vista, and XP, plus Windows Server 2008 and 2003.

Only Windows 7, Vista, XP, and 2000 are said to be the only supported operating systems, but I used HD Tune in Windows 10 and Windows 8 without any issues.

Samsung HUTIL

Samsung HUTIL
What We Like
  • Tests hard drives regardless of the OS that's installed

  • Not too difficult to use

What We Don't Like

  • Hasn't been updated in many years

Samsung HUTIL is a free hard drive diagnostic utility for Samsung hard drives. HUTIL is sometimes called ES-Tool.

This tool is available as an ISO image for burning to a CD or USB drive. This feature makes HUTIL operating system independent and a better testing tool, in general, than those designed for use within Windows. It's also possible to run HUTIL from a bootable floppy disk.

Because this is a bootable program, you'll need a working hard drive and OS to burn it to a disc or USB device. 

HUTIL will only test Samsung hard drives. It will load and find your non-Samsung drive but you will not be able to run any diagnostics on the drive.

Two tests are available: A "Quick Test" (about three minutes) and a "Comprehensive Test" (time will vary based on hard drive size).

The Windows version is said to work with Windows 8, 7, Vista, and XP. It might also run just fine in Windows 11 and Windows 10.

The report of either test can be read straight from the program when complete, configured to be sent to you by email or printed off.

Free EASIS Drive Check is said to work with Windows 2000 through Windows 7, but I successfully tested it in Windows 10 and 8 as well.

Ariolic Disk Scanner

Ariolic Disk Scanner v1.7
What We Like
  • Checks any hard drive for bad sectors

  • Shows which files are affected by errors

  • Portable (no installation necessary)

  • Very clean interface that's not distracting or confusing to use

What We Don't Like
  • Doesn't support HFS (only NTFS and FAT file systems)

Ariolic Disk Scanner is similar to Macrorit Disk Scanner in that it's just a read-only scan of a drive to check for bad sectors. It has a minimal interface with only one button, and is easy to understand if any parts of the drive contain bad sectors.

One thing that's different from Macrorit Disk Scanner is that Ariolic Disk Scanner lists the files where read errors occurred.

I tested Ariolic Disk Scanner in Windows 11, 10, and XP, but it should also work with other versions of Windows. The program is portable and just over 1 MB in size.
