How to Check Disk Health Windows 10: Essential Steps and Tools Guide

You can check a Windows 10 disk from several angles: the drive’s SMART health status, file-system errors, available space, and symptoms such as unusual noises or repeated read failures. No single Windows screen can guarantee that a drive will not fail.

Check the drive health shown by Windows

On systems where Windows exposes the feature for the installed storage, open Settings > System > Storage and look under the advanced storage or disk-management options for drive health information. Windows’ health monitoring is more complete for some NVMe SSDs than for many older SATA drives, so the absence of a detailed health page is not proof that the disk is healthy.

Use the drive manufacturer’s diagnostic utility

For an SSD or hard drive from a known manufacturer, its official diagnostic application can provide firmware information, SMART attributes, self-tests, and health estimates specific to that hardware. Download such tools from the drive or computer manufacturer’s official support site rather than from generic driver-download pages.

Check the file system

  1. Open File Explorer and choose This PC.
  2. Right-click the drive and select Properties.
  3. Open the Tools tab.
  4. Under Error checking, choose Check.

This checks file-system integrity. It is not the same thing as a comprehensive physical-health test.

Command-line checks

Windows also provides chkdsk for checking volumes. Run repair options only when you understand what they will change. If a disk is clicking, disconnecting, producing many read errors, or contains irreplaceable data, make a backup—or seek professional recovery—before stressing the drive with repair scans.

Warning signs deserve more weight than a “healthy” label

Back up immediately if files repeatedly become corrupt, the drive vanishes from Windows, SMART warnings appear, or the PC experiences storage-related errors. SMART monitoring can identify many developing failures but cannot predict every sudden electronics or mechanical failure.

Keep backups even when the disk looks healthy

Disk-health tools are diagnostic aids, not backups. Maintain separate copies of important files so a drive failure, theft, malware incident, or accidental deletion does not become a data-loss emergency.

Windows 10 consideration

For this guidance, remember that Windows 10’s standard free-support period ended October 14, 2025; post 60778 should be maintained with that lifecycle in mind. If the PC is capable of running a supported Windows version, operating-system migration should accompany hardware maintenance rather than relying indefinitely on a legacy installation.
