Top 4 Free Hard Drive Testing Tools

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 are built in to your operating system already and are ready to use right now while others are available from your hard drive manufacturer.
If you're interested, there are some slightly more costly but arguably better third-party hard drive testing tools available.

2. Seagate SeaTools
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 disk or CD making it highly reliable.
SeaTools for Windows is a program that installs on your Windows system but it really easy to use. 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.
