A front-end to the smartctl tool included with Windows.

HDD Guardian is an application which provides a front-end for smartctl, a utility which monitors your hard drive(s) for health status, taking advantage of S.M.A.R.T.

The application checks S.M.A.R.T attributes every 4 hours to ensure your hard drive is healthy. It is also able to enable and disable certain settings of your hard drive, settings which are normally only available to advanced users with knowledge of how to use the smartctl tool.

Information provided by HDD Guardian includes overheating, possible failure, data loss and more.

Other features included with this program are the options to run manual tests, run tests on connected external hard drives and view detailed information about connected hard drives.

HDD Guardian also includes detailed error logging, a nice feature to have when searching for any errors you run into.
