3 main features of SeaTools

The main purpose of SeaTools utility is to detect errors in your hard drive performance and find out whether it should be replaced on a warranty.

Tests are provided in order to check the current state. As a result of it, detailed information on its performance and the status of each test is displayed.

One of such tests is Acoustic Test which allows you to detect problems, if your hard drive makes suspicious sounds. For such purpose SeaTools accelerates and stops an HDD so that you can hear how it works and check if it makes “unhealthy” noise.

Another feature is the repair of bad sectors on SATA hard drives and external USB flash drives. If bad sectors are found after testing, not only SeaTools will display errors, but it will also offer you to fix them (replace the damaged blocks with backup ones). Thus, this bad sector will no longer be used by your operating system.

We should also highlight the reading of SMART-attributes. SeaTools reports on the status of your HDD as well as on the characteristics of your drive. This information will be useful for checking the status of your hard drive.

Conclusion. SeaTools is an effective and free tool which will be useful for diagnosing and monitoring your HDD status. It's wise to use this program at least occasionally in order to prevent a sudden disk failure along with a loss of data.
