I am running SpinRite 6 on a dying hard drive. What do all these terms mean on the SMART Monitor screen?

  • ECC Corrected
  • Realloc Events
  • Seek Errors
  • Recal Retrires
  • Cabling Errors
  • Uncorrectable
  • Write Errors

Scroll to the bottom of this if the info is not in any of those links, contact the author Steve Gibson. – Moab Feb 27 '11 at 20:39
^ Thanks but the site doesn't list any info about it. I'll look into contacting the author. – Chris Tarazi Feb 27 '11 at 20:58

It looks like those are abbreviations of S.M.A.R.T. attribute names.

My guess:

  • ECC Corrected - The sector was read multiple times and was recovered by combining the different results.
  • Realloc Events - Sectors that were reallocated elsewhere.
  • Seek Errors - Sectors that could not be reached (the seek failed)
  • Recal Retries - How many attempts to recalibrate were made.
  • Cabling Errors - Errors due to the interference (noise in the cables?)
  • Uncorrectable - Sectors that could not be recovered
  • Write Errors - Sectors that gave an error when written (Spinrite --depending on the configured mode-- first reads the sector, then writes it again, making sure it's still in good health)

With ECC you should not need to read multiple times. Assuming single/few bit errors you can correct with a single reading. FOr a very simple example how corrections occur see this. – Hennes Dec 7 '13 at 16:36
