|---|---|---|
| Reallocated Sector Count | Number of sectors remapped due to errors. | Indicates increasing drive wear and potential impending failure. |
| Current Pending Sector Count | Number of unstable sectors waiting to be remapped. | Indicates potential future errors and data loss. |
| Uncorrectable Sector Count | Number of sectors that could not be corrected. | Indicates severe drive problems and potential data corruption. |
| Power-On Hours Count | Total number of hours the drive has been powered on. | Provides a general indication of drive usage and wear. |
| Temperature | Drive operating temperature. | High temperatures can accelerate drive wear and lead to failures. |
| Spin-Up Time | The time required for the drive to reach its full operating speed. | A longer spin-up time can indicate mechanical issues. |
| Write Error Rate | The number of reported errors in write operations. | May indicate bad sectors, overheating, bad cables, or faulty controller. |
| Read Error Rate | The number of reported errors in read operations. | May indicate bad sectors, overheating, bad cables, or faulty controller. |
Using Third-Party Diagnostic Tools
Several third-party diagnostic tools provide more detailed information about your drive’s health than the built-in tools. These tools often offer features like:
- Detailed S.M.A.R.T. attribute analysis: Provides explanations of S.M.A.R.T. attributes and their significance.
