How to Check If Your Hard Disk Is Healthy Using HDDScan

1️⃣ Select Your Drive

• Open HDDScan
• Choose the correct drive from the dropdown list
  (Be careful if you have multiple drives connected)
  

2️⃣ Check SMART Status

• Click on SMART
• Look for:
  • Reallocated sectors
  • Pending sectors
  • Read errors

✅ All values normal = good health

⚠️ Warnings or red values = risk

3️⃣ Run a Surface Test (Optional)

• Click Tests
• Choose Verify or Read
• Avoid Erase unless you know exactly what you’re doing

This helps detect bad sectors without damaging data.

When Should You Be Concerned?

You should take action immediately if:

• SMART status shows Warning / Bad
• HDDScan reports bad sectors
• Your drive is very slow or keeps disconnecting
• You hear clicking or grinding noises

⚠️ Do not keep testing a failing drive repeatedly — this can make data loss worse.

Important Safety Advice

• Always back up your data first
• Never run repair or erase tests on a failing drive
• If your data is important, stop using the drive and seek professional help
