How to Check if a Hard Drive Is Failing on Windows 10? [Easy Steps]

A failing hard drive often gives early warning signs, including slow performance, system crashes, file corruption, and disk-related errors. By using Windows 10 tools such as Error Checking, CHKDSK, SMART status, and Event Viewer, you can identify many potential issues before they lead to complete drive failure.

In Windows 10, you can use the drive manufacturer’s diagnostic utilities to perform more detailed health checks. 

In this guide, you’ll learn several easy methods to check if your hard drive is failing on Windows 10. 

How to Check if a Hard Drive Is Failing on Windows 10? [Easy Steps]

Before you begin testing your hard drive, save any work you have open and make sure your computer is connected to a reliable power source. 

If your PC has been freezing or crashing frequently, it is also a good idea to create a backup of your important files before running any diagnostic tests.

Step 1: Look for the Common Signs of a Failing Hard Drive

The first step is simply paying attention to your computer’s behavior. A failing hard drive usually shows several warning signs before it stops working completely. Recognizing these symptoms early can help you avoid losing valuable data.

Start by noticing whether your computer has become unusually slow while opening files or launching programs. If Windows takes much longer than normal to boot, your drive could be struggling to read important system files.

You should also watch for frequent freezing or random system crashes. If your computer suddenly becomes unresponsive or displays unexpected error messages while accessing files, the hard drive may contain damaged sectors.

Another common sign is hearing unusual clicking, grinding, or repeated ticking noises coming from a traditional HDD. These sounds often indicate mechanical problems inside the drive. If you use an SSD, you will not hear mechanical noises, but you may still experience slow performance or file corruption.

Other warning signs include files disappearing unexpectedly, folders becoming inaccessible, corrupted documents, or repeated messages asking you to repair the drive.

If you notice one or more of these symptoms regularly, continue with the following diagnostic steps to confirm whether your hard drive is developing problems.

Step 2: Check the Drive for Errors Using Windows Error Checking

Windows 10 includes a built-in utility that scans your drive for file system errors and attempts to repair them automatically. This is one of the easiest ways for beginners to check drive health.

Open File Explorer by pressing Windows + E on your keyboard. Select This PC from the left side of the window. Under Devices and drives, locate the drive you want to inspect. In most cases, this is the C: drive where Windows is installed.

Right-click the drive and select Properties. A new window will appear with several tabs. Open the Tools tab and look for the Error checking section.

Click Check. Windows will examine the selected drive for problems. Depending on your system, you may see a message stating that no errors were found, or Windows may recommend scanning the drive anyway. Allow the scan to finish without interrupting it.

If Windows detects file system issues, follow the on-screen instructions to repair them. Some repairs may require restarting your computer. Keep in mind that repairing file system errors does not necessarily mean your hard drive is physically damaged, but repeated errors could indicate that the drive is beginning to fail.

Once the scan finishes, note whether Windows reports any recurring problems. If errors continue appearing after repairs, you should continue with additional diagnostic methods to determine the overall health of your drive.

Step 3: Run the CHKDSK Command to Scan for Bad Sectors

If you want a more detailed scan, Windows 10 includes the CHKDSK utility. This tool checks your drive for file system errors, identifies bad sectors, and attempts to recover readable information from damaged areas of the disk. It is one of the most reliable built-in tools for diagnosing hard drive problems.

Begin by typing Command Prompt into the Windows search bar. Right-click Command Prompt and select Run as administrator. This opens an elevated Command Prompt window with the permissions needed to scan and repair your drive.

Type the following command and press Enter:

chkdsk C: /f /r

Replace C: with the appropriate drive letter if you want to check a different drive.

The /f parameter tells Windows to fix file system errors automatically, while the /r parameter scans for bad sectors and tries to recover readable data.

If you are scanning your Windows drive, you will likely receive a message stating that the drive is currently in use. Windows will ask whether you want to schedule the scan the next time the computer restarts. Type Y and press Enter.

Restart your computer. Before Windows loads, CHKDSK will begin scanning the drive. Depending on the drive size and the number of files stored on it, this process can take anywhere from several minutes to a few hours. Avoid turning off your computer while the scan is running.

After Windows starts normally, review the scan results. If CHKDSK reports numerous bad sectors or recurring disk errors, your hard drive may be reaching the end of its lifespan. At that point, backing up your files should become your highest priority.

Step 4: Check the Hard Drive’s SMART Status

Modern hard drives and solid-state drives include a built-in monitoring system known as SMART, which stands for Self-Monitoring, Analysis, and Reporting Technology. SMART continuously monitors the health of the drive and can warn you if hardware failure is becoming likely.

Open Command Prompt as an administrator again.

Type the following command and press Enter:

wmic diskdrive get status

Within a few seconds, Windows will display the health status of your installed drives.

If you see OK, Windows has not detected any immediate hardware issues through SMART monitoring. This generally indicates that the drive is functioning normally.

If the status displays Pred Fail, Unknown, or another warning instead of OK, it means the drive has reported potential hardware problems. Although the drive may still work, it should be considered unreliable. Immediately create a backup of your important files and begin planning for a replacement drive.

Keep in mind that SMART monitoring is helpful but not perfect. A drive can sometimes fail suddenly without displaying any SMART warnings. This is why using multiple diagnostic methods provides a more accurate picture of your drive’s condition.

Step 5: Use the Drive Manufacturer’s Diagnostic Tool

If you want a deeper analysis than Windows can provide, consider using the diagnostic software offered by your hard drive’s manufacturer. These tools communicate directly with the hardware and often provide more detailed health information.

First, identify the brand of your hard drive. You can do this by opening Device Manager, expanding Disk drives, and noting the manufacturer’s name.

Most major storage manufacturers offer free diagnostic software that can perform quick health checks, extended surface tests, firmware verification, and SMART analysis. These utilities are specifically designed for their own drives, making them highly reliable for identifying developing hardware issues.

Install the appropriate diagnostic tool, launch it, and select your hard drive from the available list. Most utilities offer both a Quick Test and an Extended Test. Start with the Quick Test, then run the Extended Test if the Quick Scan detects any concerns or if you continue experiencing disk-related issues.

Once the testing is complete, carefully review the results. If the software reports failing sectors, read errors, or hardware failures, replace the drive as soon as possible. Continuing to use a failing drive increases the risk of permanent data loss.

Step 6: Review Disk Errors in Event Viewer

Windows automatically records many hardware and storage-related events in Event Viewer. Reviewing these logs can help you identify recurring disk errors that may not be obvious during everyday computer use.

Press Windows + X and select Event Viewer.

Expand Windows Logs and then choose System. The System log contains information about hardware events, driver activity, and storage-related issues.

Select Filter Current Log from the right side of the window. You can filter for common disk-related event sources, such as Disk, Ntfs, or DiskDiagnostic to make the results easier to review.

Look for repeated warnings or error messages mentioning bad blocks, read failures, delayed write failures, or disk communication problems. Occasional entries may not be cause for concern, but frequent disk-related errors often indicate an underlying hardware issue.

If Event Viewer consistently reports storage errors along with symptoms such as slow performance, file corruption, or system crashes, there is a strong possibility that the hard drive is failing. Back up your important data immediately and consider replacing the drive before the problem becomes more severe.

Additional Tips

Checking your hard drive regularly can help you detect problems before they become serious. If your computer stores important work documents, family photos, or other valuable files, create backups on an external drive or a trusted cloud storage service. A backup ensures that your data remains safe even if the hard drive fails unexpectedly.

Keep your computer properly ventilated because excessive heat can shorten the lifespan of both HDDs and SSDs. Running Windows updates and storage firmware updates can also improve drive stability and compatibility. If you notice repeated disk errors, unusual noises from a traditional hard drive, or frequent file corruption, avoid delaying a replacement. Replacing the drive early is often much less expensive and stressful than attempting professional data recovery after a complete failure.
