Check HDD Health on Linux


HDD is (currently, used to be) one of the most crucial parts of a computer. It works as the BULK data storage. With the help of a number of magnetic disks, motors, and sensors, your HDD is always keeping your system and ultimately, yourself happy while tolerating all the TORTURES you’re putting on your system.

Jokes aside, HDD health is a really big concern. It’s because HDDs don’t die in just an instant. They continue to wear out gradually over time and one day, you may have just lost some of your oldest photos or your favorite movie collection or even worse, your important office document!

Before that happens, continue to keep checking your HDD status. If you’re on Linux, it’s time to get these tools right now!
