6 Ways to Check Hard Disk Health in Windows 10

How To Check Hard Disk Health On Windows 10 Featured

Your hard drive is the soul of your PC, the place where all your most important data is stored. While most PC components can be replaced, the invaluable data on your hard drive can’t unless you have a recent backup. For this reason, ensuring your hard drive stays healthy is crucial. That’s why it’s important to check your hard disk health on Windows 10.

There are various ways to check this – from built-in methods in Windows to your HDD manufacturer’s diagnostic tools. You can use all or just one of the methods below, depending on your preferences.

1. Check the BIOS

As long as you’re using a relatively modern motherboard, you can run hard drive checks in the BIOS, free from any OS-based interference.

Reboot your PC, and after it’s switched off and on again repeatedly, pressing Delete, F2, F12, or whichever button the boot screen tells you, will take you to your BIOS. You can also set Windows 10 to boot directly into the BIOS.

Once in the BIOS, the exact instructions will depend on your motherboard manufacturer. On my MSI Mortar WiFi B550M in the BIOS, I can go to “Settings -> Advanced -> NVME self-test” to test the health of my NVMe drives.

While you’re in the BIOS, it’s also a good place to see whether the hard drive you want to check is actually being detected by your PC/motherboard.

On Dell and HP laptops, you should be able to check hard drive health by going to the BIOS and looking for “Diagnostics.”

2. Optimize and Defrag in Windows 10

Traditional SATA hard drives may have largely made way for much faster solid-state drives, but they’re still very popular and remain an affordable way to store things like pictures, videos and other non-strenuous file types. SSDs work a little differently, and while they never need defragmentation (because fragmentation relates to where the data is physically stored on the drive, which isn’t a factor on SSD), they do sometimes need optimizing.

If you feel like your non-SSD hard drive is slowing down, then you should check to see how fragmented it is. You can do this using Windows 10’s built-in defrag tool (typing “defrag” in the Start menu, then going to “Defragment and Optimize Drives”), then selecting the drive and clicking “Analyze.” If fragmentation gets detected, click “Optimize” (formerly called “Defrag”) for that drive.

You can also right-click drives in File Explorer, select “Properties,” choose “Tools,” and press “Optimize.”

We actually found that the free app Defraggler does a better job of detecting and reducing fragmentation, but not everyone wants to install extra apps when the functionality is built right into the OS. MyDefrag is another great option.

You can also optimize your SSD on the Windows 10 defrag and optimize tool, though Windows 10 should be taking care of the process automatically.

3. Use the HDD Manufacturer’s Tools

Most major hard drive manufacturers provide free robust tools to monitor your hard drive health and performance. The first step to knowing which one to use is, of course, knowing the make of your hard drive.


If you know the make of your hard drive, you can skip this part. If you don’t, press the Win key, type “device manager,” and click when it appears in the search results.

In Device Manager, unstack the “Disk drives” option and make a note of the model number of your hard drive. Next, type the model number into Google to bring up results that will show you the make of the hard drive.


After that, go to the manufacturer’s support page and search for its hard drive utility. To help you out, the following are links to the relevant download pages of some of the biggest hard drive brands:

Each of these tools functions a little differently, but most importantly, each one has diagnostic features that let you test your hard drive health.

4. Windows CHKDSK Tool

The Windows CHKDSK tool is a built-in Windows tool that will scan your disk to find system errors and bad sectors. It also helps check hard disk health by showing you any errors. It’ll both scan and fix problems (if possible) and will let you know if there is a bigger problem that it can’t fix. You can use this tool to both check disk health and fix bad sectors and errors if possible.

To use CHKDSK, open File Explorer, right-click on the drive you would like to check for errors, select “Properties,” and click on the “Tools” tab. Press “Check.”

You’ll get a message stating “You don’t need to scan this drive” in most cases. This is because Windows 10 automatically scans for disk health issues. However, you can still run a manual scan if you want.

5. Use WMIC

WMIC is a command-line interface that lets you perform many administrative tasks, including checking hard disk health. It uses the S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) feature of hard disks to see the status and provide a simple conclusion, like “OK,” “Pred Fail,” etc. It is still a very basic command that offers very little information but is a quick built-in feature of Windows.

To check a hard disk with WMIC, press the Win + R buttons to open the Run dialog. Type cmd and click “OK” to open the Windows command prompt.

and hit Enter. When the WMI interface is ready, type:

and press Enter again. You will see the status of your hard disk after a short delay.

6. Use a Third-Party Hard Disk Health Checking Tool

You can also use a third-party hard disk health checking tool that will offer much more information than just good or bad status. These tools use the same “S.M.A.R.T” feature of hard disks to fetch data, just like WMIC. However, they provide far more detail instead of just showing good or bad status.


For this purpose, CrystalDiskInfo is a really simple, yet powerful, tool. It is a free-to-use tool that is extremely light and offers all the required information, such as temperature, health status, hard disk type and features, and other attributes, like read/write error rate, spin-up time, etc.

When you download and extract the files, select the right tool for your Windows 10 version. For me, I’d choose the 64-bit version. Select either “DiskInfo32” or “DiskInfo64.” This runs the tool without installing anything.

When you select the tool, nothing happens for around 10 seconds, until you see a full report.

In the Function menu, you can select more advanced options. You can even have it check hard disk health at startup.

There are also other third-party hard disk health-checking tools like Hard Disk Sentinel and HDDScan. These are much more advanced with loads of extra features, but for an average user, CrystalDiskInfo should work perfectly.

You can use the above-mentioned tools to check hard disk health on Windows 10. If you don’t need extra details, then the Windows built-in tools should work great.
