How to Check Hard Disk Health on Windows | HDD & SSD Health Test
Check the health of an HDD or SSD on Windows and learn how drive condition information can help identify potential storage problems before important data is affected.

Check Hard Disk Health on Windows
Storage drives contain your operating system, applications, documents, photos and other important data.
Checking the condition of an HDD or SSD can help identify warning signs and determine whether additional diagnostics or a backup should be considered.

How to Check HDD Health
Traditional hard disk drives contain mechanical components. Problems can sometimes appear as unusual noises, slow file access, read errors, system freezes or drive-health warnings.
A disk-health utility can provide information reported by the drive that can help during troubleshooting.
How to Check SSD Health
Solid-state drives do not contain the same moving mechanical parts as traditional hard drives, but SSDs can still experience wear, controller problems or other failures.
Supported SSDs may report health, temperature, reliability and remaining-life information.
What Is S.M.A.R.T. Disk Health?
S.M.A.R.T. stands for Self-Monitoring, Analysis and Reporting Technology.
Many HDDs and SSDs maintain internal reliability information that diagnostic software can use when evaluating drive condition.
The exact attributes and interpretation can vary between drive manufacturers and storage technologies.
Possible Signs of a Hard Drive Problem
- Very slow file access
- Unexpected disk errors
- Files becoming unreadable
- Frequent Windows freezes during disk activity
- Drive-health warnings
- Unexpected HDD noises
- Storage device disappearing intermittently
- Repeated read or write problems
These symptoms do not automatically prove that a drive is failing, but they are reasons to investigate further.
Back Up Important Data First
If a disk is showing serious warnings or unusual behaviour, protect important files before performing unnecessary stress tests or making major changes.
No health-monitoring tool can guarantee that a drive will not fail unexpectedly.

Disk Health vs Disk Space
Disk health and available disk space are different problems.
A healthy drive can still be almost full, while a drive with plenty of free space can still develop hardware or reliability problems.
If your problem is a full C drive rather than drive health, use the storage-analysis guides below.
Hard Disk Health Frequently Asked Questions
Can Windows check HDD health?
Windows and compatible diagnostic tools can provide useful information about supported storage devices and their reported condition.
Can I check SSD health?
Yes. Many SSDs provide reliability and health information that can be inspected using compatible tools.
What should I do if my disk health is bad?
Back up important data promptly. Then investigate the drive and consider replacement if diagnostics indicate a developing hardware problem.
Can a disk fail even if health looks good?
Yes. Health information is useful for identifying some problems, but it cannot predict every possible drive failure.
