How do I fix Windows found errors on this drive?

Dealing with hard drive errors in Windows can be frustrating, but fixing them is possible if you follow the right steps. Hard drive errors typically appear when Windows detects file system corruption or bad sectors on your drive. Thankfully, Windows has built-in tools that can help identify and repair these problems.

What Causes Hard Drive Errors in Windows?

There are a few common causes of hard drive errors in Windows:

  • File system corruption – The file system manages how data is stored on your drive. If it becomes corrupted, Windows may not be able to properly access files on the drive.
  • Bad sectors – These are physical defects on the hard drive platters. They prevent data from being stored or read properly.
  • Failing hardware – Issues with the hard drive’s mechanical components can lead to errors.
  • Sudden power loss – An unexpected power outage while Windows is writing data to the drive can cause file system corruption.
  • Driver conflicts – Outdated or buggy hard drive drivers can sometimes cause Windows to detect errors.
  • Virus infection – Viruses and malware can sometimes corrupt or overwrite data on a hard drive, triggering errors.

How to Check for Hard Drive Errors in Windows

If Windows is detecting drive errors, the first step is to analyze your drive to identify the problem. Here are some ways to check for errors:


CHKDSK is a built-in Windows command line tool that scans your drive and looks for logical file system errors. To run it:

  1. Open the Command Prompt as administrator.
  2. Type “chkdsk C: /f” (without quotes) and hit Enter. Replace C: with the letter of your hard drive.
  3. CHKDSK will scan the drive and repair any file system problems it finds.

Use Disk Checking in Windows

Alternatively, you can use the built-in Disk Checking tool:

  1. Open File Explorer, right-click your hard drive, and select Properties.
  2. Go to the Tools tab and click “Check”. This will launch Disk Checking.
  3. Allow Disk Checking to scan your drive and repair any errors.

Check S.M.A.R.T. status

S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) checks your hard drive’s mechanical condition. To view it:

  1. Open Windows’ Control Panel.
  2. Click System and Security, then Administrative Tools.
  3. Double-click Computer Management, go to Storage > Disk Management.
  4. Right-click your disk and select Properties. Go to the Tools tab.
  5. Under S.M.A.R.T. status, check for any errors or indicators of drive failure.

Use Third-Party Tools

Software like HD Tune Pro also analyzes hard drives and checks for health issues or bad sectors. These tools provide more detailed drive information compared to Windows’ built-in utilities.

Fixing Common Hard Drive Errors

Once you’ve diagnosed the issue, you can work on resolving it. Here are some fixes for the most common hard drive errors:

Repair File System Errors

As mentioned, CHKDSK can automatically fix file system corruption. Run it regularly to scan and repair any logical errors on your drive. Disk Checking in Windows also repairs file system issues.

Resolve Bad Sectors

Bad sectors can be “remapped” so they are no longer used for data storage. This prevents data loss or corruption. In Disk Management, right-click your disk and choose Properties > Tools. Click “Scan Now” under Error checking to search and remapp bad sectors.

Replace Failing Hardware

If S.M.A.R.T. indicates hardware problems, it’s best to replace the aging hard drive. Cloning the drive to a new one will allow you to salvage your data before the old drive completely fails.

Diagnose Driver and Software Issues

Update your hard drive’s drivers to the latest versions offered by the manufacturer to resolve any compatibility bugs. An antivirus scan can also determine if malware is contributing to drive errors.

Restore Data from Backup

If all else fails and your drive is unrecoverable, you may need to erase it and restore your data from a recent backup. It’s critical to regularly backup your drive to prepare for this scenario.

Best Practices to Avoid Hard Drive Errors

Practicing proper hard drive maintenance can help prevent errors and failure down the road:

  • Regularly backup your data – Backups ensure you won’t lose critical files if your drive fails.
  • Scan for errors with CHKDSK – Run CHKDSK regularly to detect and repair file system problems.
  • Monitor S.M.A.R.T. status – Keep an eye on S.M.A.R.T. to catch any mechanical issues before they escalate.
  • Ensure proper ventilation – Hard drives need air circulation to stay cool. Make sure your PC case has adequate airflow.
  • Update drivers and OS – Outdated drivers and Windows can sometimes create incompatibility issues that affect the drive.
  • Practice safe computer use – Things like sudden power loss while writing data, malware infections, and excessive drive vibrations can eventually cause errors.

Recovering Data from a Drive with Errors

If your hard drive already has critical errors – making it unbootable or inaccessible – there may still be hope for recovering your files:

Try Data Recovery Software

Programs like Recuva, EaseUS Data Recovery, and Stellar Data Recovery scan drives for recoverable files. They may be able to salvage documents, photos, and other data from the drive.

Boot to a Live CD/USB

Booting to a Linux live CD or USB drive can sometimes allow you to access an error-ridden drive just enough to copy your important files from it to an external drive.

Remove the Drive for Recovery

As a last resort, you can remove the hard drive and connect it to another computer as an external drive. This may provide temporary access to recover any accessible data.

Consult a Data Recovery Service

For extreme cases of hard drive problems, a professional data recovery service can disassemble the drive in a cleanroom and repair it long enough to recover some data. However, this can be expensive and is not guaranteed.

How to Avoid Data Loss from Drive Errors

Your best protection against data loss is prevention. Here are some key tips:

  • Backup regularly – Backup to an external drive or cloud storage on a daily or weekly basis.
  • Use file history – Windows’ file history continually backs up versions of your data.
  • Store data redundantly – Save important files and backups in multiple locations.
  • Use RAID – RAID 1 mirrors drives for redundancy, protecting data if one drive fails.
  • Replace drives proactively – Swap out older hard drives before they fail.
  • Verify backups – Occasionally confirm backups can be restored properly.

Frequently Asked Questions

Why does my hard drive show errors even though CHKDSK found no problems?

This can occur if the errors are being caused by bad sectors rather than file system corruption. CHKDSK only scans for file system errors, while Disk Checking also checks for physical defects like bad sectors. Running the “Scan Now” tool may find and remap any bad sectors to fix the error messages.

How long does CHKDSK take to scan a drive?

The time it takes CHKDSK to scan a drive depends on the size of the drive and severity of errors. A quick scan of a healthy 1TB drive can take 5-10 minutes, while a full scan of a damaged 4TB drive with extensive errors to repair could take 4+ hours.

Can I use my computer normally while CHKDSK is running?

No, you cannot use the computer normally while CHKDSK is scanning the drive. CHKDSK will require exclusive access to the drive. You can still use the computer for basic tasks, but running intensive apps that require hard drive access will be slow.

What happens if I interrupt CHKDSK mid-scan?

Interrupting CHKDSK is not recommended, as this can further corrupt the file system. If the scan is interrupted, the next time you run CHKDSK it will start over from the beginning. Allow CHKDSK to run until completion, even if it takes several hours.

Can bad sectors be repaired or are they permanently damaged?

Strictly speaking, bad sectors cannot be repaired. These are physical defects on the hard drive platters. However, they can be remapped to prevent data from being stored there again. Essentially the sectors are marked as “bad” so they won’t be used anymore.

How long does a hard drive typically last?

It depends on usage and conditions, but most new hard drives can last somewhere between 3 to 5 years before encountering errors. High-workload drives in harsh environments may only last 1-2 years. Following best practices for drive maintenance can extend the lifespan.

What are the signs my hard drive is failing?

Signs include increasingly frequent errors, loud clicking or grinding noises from the drive, much slower drive performance, inability to access files, and abnormal S.M.A.R.T. results. If you notice any of these issues, immediately backup your data and consider replacing the drive.

Can I backup my data if my hard drive is corrupted?

It depends on the severity of the corruption. With minor errors, you may still be able to manually backup your important files to an external drive or cloud storage. But with major file system corruption, the drive may be completely inaccessible for normal backup. This is why it’s crucial to maintain regular backups before problems occur.

Should I upgrade to an SSD to avoid drive errors?

SSDs have advantages like faster speeds, lower power consumption, and shock resistance. But SSDs aren’t necessarily more resistant to file corruption than hard disk drives. An SSD may help avoid errors related to physical failure, but you’ll still need to practice regular maintenance and backups.


Diagnosing and fixing hard drive errors in Windows has several steps:

  1. Use built-in tools like CHKDSK and Disk Checking to detect errors.
  2. Analyze S.M.A.R.T. status to check drive health.
  3. Repair file system corruption and remapp bad sectors.
  4. Troubleshoot hardware failure, drivers, and software issues.
  5. Recover data and restore from backup if necessary.

Following best practices for ongoing drive maintenance can help avoid most errors in the first place. But if your hard drive does start to develop problems, using the appropriate Windows tools and recovery techniques will hopefully get it working again and keep your important data intact.
