    • SMART reports bad sectors, wipe drive, now ok?

      As the title says, I have a drive that SMART reported as having a few bad sectors. I did a complete wipe of the drive and now SMART gives the drive a green light. Should I continue to use the drive or pursue an RMA? What do you guys think? SMART information attached.

    • It's Smart Stat 5, the "reallocated sector count", that's the worry.

      There are spare sectors on a drive, in the event that a few fail. That's where the term, "reallocated" comes into the picture. When the drive is reformatted, from the file system's view point, a few bad sectors may disappear. (But a potential underlying problem does not.)

      You have a threshold of 140 and a value of 200... The question is, how high does the count have to go before WD will let you do an RMA? If you can get a new drive under warranty, I'd go for it.
      _______________________________

      For reference, if a drive is heading toward failure, the following SMART stat's start incrementing:

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

    • Out of curiosity, how old are these drives?

      There's a difference between powered on hours (in your stat's) and actual age.
