💻 2. Check HDD or SSD Health Using Windows PowerShell

Windows provides built-in commands that can report basic storage health information. The availability of detailed information depends on the drive, controller, and storage driver.

📌 Method 1: Check Physical Disk Health

Steps:

1️⃣ Press Windows + X.

2️⃣ Open Terminal (Admin) or Windows PowerShell (Admin).

3️⃣ Run this command:

Get-PhysicalDisk |
Format-Table FriendlyName, MediaType, HealthStatus, OperationalStatus, Size -AutoSize

What to check:

🟢 Healthy – Windows reports the device as healthy.
🟡 Warning or another unexpected status – Investigate the device and review available diagnostics.
🔴 Unhealthy or a failed operational state – Back up important data and investigate promptly.

Note: A Healthy result does not guarantee that a drive cannot fail.

📌 Method 2: Check Storage Reliability Information

Run:

Get-PhysicalDisk | Get-StorageReliabilityCounter |
Format-List *

Where supported, the output may include:

🌡️ Temperature
⏱️ Power-on hours
✍️ SSD wear information
📊 Read and write error counters
⚠️ Other reliability indicators

Some devices do not expose all these values through Windows.

📌 Method 3: Check Basic Disk Status

Run:

Get-CimInstance Win32_DiskDrive |
Select-Object Model, Status, Size

This provides basic device information and a Windows-reported status. It is not a complete hardware diagnostic.

🩺 3. Check Disk Errors Using CHKDSK

CHKDSK checks the file system for certain logical errors. It does not replace a hardware health test.

Command:

chkdsk C: /scan

🔹 /scan performs an online scan of the supported NTFS volume.

🔹 Replace C: with the appropriate drive letter if necessary.

⚠️ If the drive is failing, disconnecting, or making unusual noises, prioritize protecting the data before running intensive scans or repair operations.

📊 4. Important HDD and SSD Health Indicators

💽 HDD Health Indicators

🔹 Reallocated Sectors: Increasing counts may indicate that the drive is replacing defective sectors.

🔹 Current Pending Sectors: Nonzero or increasing values can indicate sectors that the drive cannot currently read reliably.

🔹 Uncorrectable Errors: Review these according to the drive manufacturer's documentation.

🔹 Temperature: Compare readings with the manufacturer's recommended operating range.

⚡ SSD Health Indicators

🔹 Percentage Used: Indicates estimated endurance consumed on supported drives.

🔹 Available Spare: Shows remaining spare capacity on supported NVMe SSDs.

🔹 Media and Data Integrity Errors: Review any reported errors.

🔹 Critical Warning: Investigate any reported critical warning immediately.

🔹 Temperature: Check whether the SSD is operating within its recommended range.

💡 Important: S.M.A.R.T. attributes differ between manufacturers. Do not judge a drive solely by one attribute or a single health percentage.

🚨 5. Warning Signs of HDD or SSD Failure

Watch for these symptoms:

⚠️ Computer freezes frequently.

⚠️ Files become corrupted or inaccessible.

⚠️ Windows reports disk or storage errors.

⚠️ The drive disappears unexpectedly.

⚠️ HDD makes clicking or grinding sounds.

⚠️ SSD reports critical warnings or media errors.

⚠️ File transfers become unusually slow or fail repeatedly.

What should you do?

1️⃣ Back up important data if the device remains safely accessible.

2️⃣ Check the drive's health and diagnostic reports.

3️⃣ Avoid unnecessary writes, formatting, or repair attempts.

4️⃣ For clicking or mechanically damaged HDDs, stop using the device and seek professional recovery assistance if the data is important.

5️⃣ Replace a drive when diagnostics and manufacturer guidance indicate failure.

🔐 6. Best Practices for IT Administrators

For business computers, servers, and critical systems, follow these practices:

✅ Monitor drive health periodically.

✅ Maintain verified backups of important data.

✅ Test data restoration regularly.

✅ Record drive model, serial number, capacity, and health status in the IT asset inventory.

✅ Review hardware alerts and storage event logs.

✅ Use manufacturer-approved diagnostic tools where possible.

✅ Replace failing drives according to an approved maintenance process.

✅ For RAID and server storage, check the storage controller and array status as well as individual drives.

💡 Remember: RAID is not a substitute for a backup. Critical business data should have a separate, tested recovery strategy.

❓ Frequently Asked Questions (FAQs)

🔹 Which tool is best for checking HDD and SSD health?

CrystalDiskInfo is a convenient starting point for viewing available S.M.A.R.T. information. Manufacturer diagnostic utilities can provide additional tests.

🔹 Can I check HDD health without installing software?

Yes. Windows PowerShell can show basic storage health information, although detailed reliability data depends on hardware and driver support.

🔹 Does 100% SSD health mean the SSD is safe?

No. A health or endurance indicator does not guarantee that the SSD will never fail.

🔹 Is CHKDSK enough to check drive health?

No. CHKDSK checks file-system integrity. Use appropriate hardware diagnostics and available S.M.A.R.T. information to assess drive condition.

🔹 How often should I check disk health?

Home users should check periodically and whenever problems occur. IT teams can use more frequent monitoring for business-critical devices.

🎯 Conclusion

Checking HDD and SSD health is an important part of preventive IT maintenance. Tools such as CrystalDiskInfo, smartmontools, Samsung Magician, and Seagate SeaTools can help identify warning signs, while Windows PowerShell provides useful built-in status information.
