If you want an even deeper, more accurate picture into your drive's health, check its manufacturer's website for a dedicated tool. So that 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, my drive above has a few bad and reallocated sectors, and I haven't 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. information than your computer provides on its own.

For a closer look, I recommend downloading CrystalDiskInfo (Opens in a new window) for Windows (free), or DriveDx (Opens in a new window) for macOS ($20 with a free trial), both of which will offer up more detailed S.M.A.R.T. You only know when your drive is near death, but you can start to experience problems even if the basic S.M.A.R.T. That means even if your drive isn't making strange noises, you should keep an eye on its health once in a while, so you can prepare for death before it happens. Unless your drive experiences excessive heat or physical trauma, it'll probably fail gradually. Newer solid-state drives (SSDs) don't have moving parts, but their storage cells degrade a little bit every time you write to them, meaning they too will eventually fail (though SSD reliability is much better than it used to be).
On older spinning drives, moving parts like the motor can degrade over time, or the drives' magnetic sectors can go bad. This is normal, especially if your drive is more than a few years old. Strange noises, corrupted files, crashing during boot, and glacial transfer speeds all point to the inevitable end. It might be time to say farewell, but here's what you should do before it goes to the big data center in the sky.Įvery hard drive dies eventually, and when it's near death, you'll see the signs. It's starting to make clicking or screeching noises, it can't seem to find your files, and it's moving really slowly.
Your hard drive hasn't been acting the same lately.
