12 Free Hard Drive Testing Programs

A List of the Best Free Hard Drive Test Software Available


There are many free hard drive testing tools available to help you determine what, if anything, is wrong when you suspect there may be a problem with a hard drive.

Some of these tools may be built in to your operating system already while others are available from hard drive manufacturers.

Important: Replace your hard drive if it fails any of your tests.

Note: Several excellent premium hard drive testing tools are available as well.

1. Seagate SeaTools

Seagate SeaTools for DOS

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

  • SeaTools for DOS supports Seagate or Maxtor drives and runs independent from your operating system on its own CD or disk, making it highly reliable.
  • SeaTools for Windows is a program that installs on your Windows system. You can do basic and advanced testing of any kind of drive - internal or external - from any manufacturer.

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

Note: You do not need to own a Seagate or Maxtor hard drive to use SeaTools.

Also, GSmartControl can run three self-tests to find drive faults:

  • Short Self-test: Takes around 2 minutes to complete. Is used to detect a completely damaged hard drive.

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

There aren't a lot of options in Bart's Stuff Test and it's not as thorough as some other tests on this list. However, it's a decent addition to your hard drive testing arsenal, especially if you're having problems testing with an ISO based tool above but want something besides the Windows default tool.

Two tests are available with Fujitsu Diagnostic Tool, a "Quick Test" (about 3 minutes) and a "Comprehensive Test" (time will vary based on hard drive size).

Note: Fujitsu Diagnostic Tool will perform hard drive tests on Fujitsu drives only. If you have any other make of hard drive, try one of the manufacturer independent tests listed toward the beginning of this list.
