S.M.A.R.T. Warnings
Your drive monitors its own health through S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology):
- Check with tools like CrystalDiskInfo (Windows) or Disk Utility (Mac)
- Look for warnings about reallocated sectors
- Monitor temperature readings
- Watch for pending sector counts
What to Do If You See These Signs

- Don't restart repeatedly - each attempt can cause more harm
- Back up what you can - if the drive is still accessible
- Contact a professional - don't attempt DIY repairs for physical issues
