While both testing tools are excellent, they are different.
Thebootableversion of SeaTools is more powerful, but is a bit more difficult to use.
SeaTools for Windows or Linux isn’t as full-featured, but it’s much easier to install.

Both programs are completely free and are highly recommended.

The tests are basic, easy to run, and generally pretty fast in our experience.
This test can really save you a lot of time if you think your hard drive is making noise.
It will spin the drive down until it’s completely idle, making the drive nearly silent.
If you no longer hear the strange noise, the hard drive was the culprit!
