Five SMART metrics to watch

Backblaze’s analysis of nearly 40,000 drives showed five SMART metrics that correlate strongly with impending disk drive failure:

  • SMART 5 – Reallocated_Sector_Count.
  • SMART 187 – Reported_Uncorrectable_Errors.
  • SMART 188 – Command_Timeout.
  • SMART 197 – Current_Pending_Sector_Count.
  • SMART 198 – Offline_Uncorrectable
