Hard Drive Error

[Mogo]

I see 4 of these types or errors in the diagnostic logs for a particular hard drive.  What does it mean and is it a cause for concern?

 

Error 4 [3] occurred at disk power-on lifetime: 32232 hours (1343 days + 0 hours)
  When the command that caused the error occurred, the device was active or idle.

  After command completion occurred, registers were:
  ER -- ST COUNT  LBA_48  LH LM LL DV DC
  -- -- -- == -- == == == -- -- -- -- --
  40 -- 51 00 00 00 05 74 e4 93 30 00 00  Error: UNC at LBA = 0x574e49330 = 23435973424

  Commands leading to the command that caused the error were:
  CR FEATR COUNT  LBA_48  LH LM LL DV DC  Powered_Up_Time  Command/Feature_Name
  -- == -- == -- == == == -- -- -- -- --  ---------------  --------------------

You should post your system's diagnostics zip file in your next post in this thread to get more informed feedback.  It is always a good idea to post this if your question might involve us seeing how you have things set up or to look at recent logs.

Sure here is the whole diagnostic file.

Looking at those diagnostics it looks like the disk you were talking about is disk11?

 

If so then I notice that disk11 has 320 reallocated sectors so the errors may have been related to that happening.   While reallocated sectors are not necessarily a problem it would be a problem if that value keeps increasing.

Yes it was Disk 11 that it was reported on.  Ok I'll monitor it and see if that keeps increasing... Thanks.
