SSD SMART Warning / CrystalDiskInfo Caution
What is this error?
CrystalDiskInfo or SSD manufacturer tool shows 'Caution' or 'Bad' health status. SMART data indicates the SSD is developing problems.
Common causes
- SSD wear reaching end of life
- reallocated sector count increasing
- uncorrectable errors detected
- SSD firmware bug reporting false SMART values
- excessive write operations
How to fix it
- Back up data immediately
- check specific SMART values
- update SSD firmware
- run manufacturer diagnostics

CrystalDiskInfo showing 'Caution' (yellow) or 'Bad' (red) for your SSD means SMART data indicates developing problems. NOT all warnings mean immediate failure, but you should take it seriously.
Critical SMART values to check:
- Reallocated Sector Count: > 0 means the SSD is mapping around bad cells. Low numbers are OK, high/increasing numbers are concerning
- Current Pending Sector Count: > 0 means sectors are waiting to be reallocated. Actively failing
- Uncorrectable Sector Count: > 0 means data was lost. Serious
- Wear Leveling Count / SSD Life Left: below 10% means the SSD is near end of life
What to do:
- BACK UP YOUR DATA NOW — before doing anything else
- Update SSD firmware from manufacturer's tool — some SMART warnings are firmware bugs
- Run the manufacturer's diagnostic tool (Samsung Magician, WD Dashboard, Crucial Storage Executive)
- If Reallocated Sectors is low and stable (not increasing), the SSD may be fine — monitor monthly
- If any value is actively increasing over days/weeks, replace the SSD soon
- For NVMe SSDs: also check 'Available Spare' — below 10% means replacement needed
- Don't defragment SSDs — it reduces lifespan. Windows should auto-TRIM instead
