Your Windows PC depends on its storage drive to save system files, apps, documents, photos, and other important data. If the drive starts developing file system problems, bad sectors, or other errors, you may notice symptoms such as slow performance, freezing, unexpected crashes, corrupted files, or Windows startup problems.
The good news is that Windows 11 and Windows 10 include built-in tools that can scan a drive for errors and repair certain problems automatically. You do not necessarily need third-party software to perform a basic drive check.
In this guide, you will learn how to scan a drive for errors in Windows 11/10 using File Explorer, Windows Settings, Command Prompt, and other troubleshooting methods.
Scan Drive For Errors in Windows 11/10 [Complete Guide]
Windows provides several ways to check storage drives. The easiest option for beginners is the Error Checking feature available through File Explorer. If Windows does not find a problem, you can still perform a deeper check using CHKDSK.
Before starting, make sure you know which drive you want to scan. Your primary Windows installation is normally stored on the C: drive, but your PC may have additional internal drives, external hard drives, USB drives, or other storage devices.
If you are checking an external drive, make sure it is properly connected before beginning the scan.
Step 1: Open File Explorer and Find the Drive
The first step is to open File Explorer and locate the drive you want Windows to check.
Press Windows + E on your keyboard to open File Explorer. You can also open it by selecting the File Explorer icon from the taskbar or Start menu.
Once File Explorer opens, select This PC from the navigation pane on the left. You should now see the available drives under Devices and drives.
Look for the drive you want to scan. For example, your primary Windows drive will usually appear as Local Disk (C:). If you have another internal drive, it may appear as D: or another drive letter.
Take a moment to confirm that you have selected the correct drive before continuing.
Step 2: Open the Drive Properties
After identifying the drive, open its Properties window. This is where Windows provides several tools for managing and checking the drive.
Go to File Explorer > This PC > right-click the drive > Properties.
For example, if you want to check your C: drive, right-click Local Disk (C:) and select Properties.
A new window will appear showing information about the drive, including its available storage space and other settings.
Do not worry if you see several tabs. The option you need is located under the Tools tab.
Step 3: Start the Windows Error Check
Now you can start Windows’ built-in drive checking feature.
Go to Drive Properties > Tools > Error checking > Check.
Windows may display a message indicating that you do not need to scan the drive because no errors have been detected. If you still want to check the drive, you can choose the option to Scan drive when it is available.
Windows will examine the drive’s file system for certain problems. The process can take some time, particularly if you are checking a large hard drive.
If you are scanning an SSD, the process may behave differently from a traditional mechanical hard drive because SSDs manage physical storage internally. Windows is primarily checking the file system and logical errors through this interface.
Step 4: Wait for Windows to Complete the Scan
Once the scan begins, allow Windows to complete the process.
The time required depends on the drive size, drive type, system performance, and type of scan being performed. Do not disconnect an external drive while Windows is checking it.
If you are checking your primary Windows drive, you may not be able to repair certain problems while Windows is actively running from that drive. In some situations, Windows may ask you to schedule the operation for the next restart.
If Windows asks you to restart your computer, save your work first and then allow the system to restart.
Step 5: Scan the Drive Using CHKDSK
If you want a more advanced method, Windows includes a command-line utility called CHKDSK. It stands for Check Disk and can examine a drive’s file system for errors.
To open an elevated Command Prompt, go to Start > type Command Prompt > right-click Command Prompt > Run as administrator.
When the User Account Control window appears, select Yes.
For a basic check of the C: drive, enter the following command:
chkdsk C:
Press Enter.
Windows will check the file system and report whether it found problems.
This basic command primarily checks the drive without immediately performing the type of repair associated with the /f option.
Step 6: Repair File System Errors With CHKDSK
If Windows reports file system problems, you can use CHKDSK with the repair parameter.
Go to Start > type Command Prompt > right-click Command Prompt > Run as administrator.
Then enter:
chkdsk C: /f
Press Enter.
The /f parameter tells CHKDSK to fix logical file system errors that it can repair.
If you are checking the Windows system drive, Windows may tell you that the drive is currently in use and ask whether you want to schedule the check for the next system restart.
Type Y when prompted and press Enter. Then restart your PC.
Windows can perform the disk check before the operating system fully loads, allowing it to work with files that are otherwise being used by Windows.
Step 7: Perform a More Thorough Drive Check
Windows also provides additional CHKDSK parameters for more extensive troubleshooting.
For example, you can use:
chkdsk C: /f /r
The /r parameter tells CHKDSK to look for readable information in bad sectors and attempt to recover it while also performing the repairs associated with /f.
This operation can take significantly longer than a standard scan. On large mechanical hard drives, it can take a considerable amount of time.
Because of that, do not start a thorough scan right before you need to use the computer. Give Windows enough time to complete the process.
Also remember that CHKDSK is not a replacement for a backup. If your drive is showing signs of physical failure, prioritize copying important files to another storage device or cloud location.
What to Do If An Error or Many Errors Are Detected?
If Windows detects an error, the first thing to determine is whether the problem is logical or potentially hardware-related.
A file system error can sometimes be repaired with Windows tools. However, repeated errors, corrupted files, frequent crashes, disappearing files, unusual noises from a mechanical hard drive, or a drive that repeatedly becomes inaccessible can indicate a more serious storage problem.
If Windows successfully repairs the errors, restart your computer and monitor its behavior. If the same errors return shortly afterward, do not simply keep running CHKDSK repeatedly without investigating the underlying problem.
Start by backing up important files. If the drive is failing physically, continued use can increase the risk of data loss.
You should also check whether Windows reports storage or hardware-related warnings. If the drive continues producing errors, consider replacing it, particularly if it is an older mechanical hard drive.
For an SSD, persistent problems can also indicate a hardware or firmware issue. Check the manufacturer’s diagnostic software if one is available for your specific drive.
How to Troubleshoot Drive Errors in Windows 11/10?
If scanning the drive does not solve the problem, work through the troubleshooting process systematically.
First, restart Windows. A temporary file system or system-level problem can sometimes disappear after a restart.
Next, check whether Windows has pending updates. Go to Settings > Windows Update and install available updates if appropriate. Keeping Windows updated can help resolve compatibility and system-level problems.
You should also check the drive’s available storage. Go to Settings > System > Storage in Windows 11. Extremely low free space can contribute to performance problems and prevent Windows and applications from working properly.
If the drive contains important files, create a backup immediately, especially if errors continue appearing.
You can also use CHKDSK from an elevated Command Prompt to perform additional checks. If Windows repeatedly schedules disk checks during startup or the same errors keep returning, treat that as a warning rather than simply dismissing it.
For mechanical hard drives, listen for unusual clicking, grinding, or repeated spinning noises. These can indicate physical hardware problems. An SSD will not normally produce mechanical noises, so other symptoms such as disappearing storage, read/write failures, or repeated system errors deserve attention.
If you suspect the physical drive is failing, the safest approach is to replace the drive after securing your important data. Software repair tools cannot fix a physically damaged storage device.
FAQs
How do I scan my drive for errors in Windows 11?
Go to File Explorer > This PC > right-click the drive > Properties > Tools > Error checking > Check. Select the option to scan the drive and follow the instructions provided by Windows.
Does Windows 11 automatically check for drive errors?
Windows performs various maintenance and diagnostic tasks automatically, but you can manually run an Error Checking scan or use CHKDSK when you suspect a drive or file system problem.
Is CHKDSK safe to use?
Yes, CHKDSK is a built-in Windows utility designed to check and repair file system problems. However, you should always maintain a backup of important data before performing extensive disk repairs.
How long does CHKDSK take?
There is no fixed duration. A basic check may finish relatively quickly, while a scan using CHKDSK /f /r can take much longer, especially on large mechanical hard drives.
Can CHKDSK fix bad sectors?
CHKDSK can identify bad sectors and attempt to recover readable information when the appropriate parameters are used. However, it cannot physically repair a damaged storage device.
Should I run CHKDSK on an SSD?
CHKDSK can be used with SSDs to address file system errors, but you should not treat it as a tool for repairing the physical NAND storage. Persistent SSD problems should be investigated using appropriate hardware diagnostics and backups.
What should I do if drive errors keep coming back?
Repeated errors can indicate an underlying hardware problem, failing drive, corrupted file system, or other system issue. Back up your important data first, then investigate the drive’s health and consider replacing it if hardware failure is suspected.
Summary
Knowing how to scan a drive for errors in Windows 11/10 can help you identify file system problems before they turn into bigger headaches. For most beginners, the easiest method is File Explorer > This PC > Drive Properties > Tools > Error checking > Check.
If you need more control, CHKDSK provides additional options for checking and repairing file system errors. The /f parameter can repair certain logical errors, while /r performs a more extensive check involving bad sectors and recovery of readable data.
Most importantly, remember that a drive scan is not a substitute for a backup. If errors keep returning, files become corrupted, or the drive behaves unpredictably, take those symptoms seriously.
Protect your important data first, then troubleshoot the underlying problem or replace the storage device if necessary.
