If you want an even deeper, more accurate picture into your drive's health, check its manufacturer's website for a dedicated tool. So a Caution label is usually a good indicator that you should back up the drive and think about replacing it soon, even if you aren't having problems yet. But if even one of those bad sectors lands on a file you need, it can be rendered corrupt. These labels apply to hard drives and SSDs that are starting to wear down, but aren't necessarily on their deathbed (read more about how CrystalDiskInfo applies those labels here (Opens in a new window)).įor example, your drive may have a few bad and reallocated sectors, and you still might not have run into any issues-probably because those bad sectors weren't housing any actual data at the time. Instead of saying your drive is OK or Bad, like the built-in tools do, CrystalDiskInfo and DriveDx also have more intermediary labels, like Caution or Warning, respectively.
