Spinrite & S.M.A.R.T.

[m1dori]

Hello,

I ran level 3 spinrite on an 8 TB drive I had sitting around and the log is attached. It did not report errors.

I have a TrueNAS Scale with one 8 TB HDD in it that kept getting ZFS pool errors without any S.M.A.R.T. errors and I could not figure out what was causing these errors. I swapped the drive that was giving errors [WDC_WD80EFPX-68C4ZN0] with the drive that I completed the level 2 scan on [ST8000VN004-3CP101]n that I had sitting around. After the swap, S.M.A.R.T errors populated on the drive that showed no errors with Spinrite.

Can someone help explain some of this? Possbily the difference in S.M.A.R.T. errors vs Spinrite? Does that mean this drive is no good? Would a level 5 have any impact on this drive? Etc....

I attached the SMART report below as well. I understand that this is not a TrueNAS forum, I am generally trying to understand hard drives more and navigate what this all means.

I appreciate your assistance greatly

It looks like your drive is only reporting uncorrectable errors on attribute 187, but also has attribute 198. SpinRite only uses 187 if 198 doesn't exist. SpinRite also doesn't check the SMART Error Log.

ID# ATTRIBUTE_NAME          FLAG     VALUE WORST THRESH TYPE      UPDATED  WHEN_FAILED RAW_VALUE
187 Reported_Uncorrect      0x0032   090   090   000    Old_age   Always       -       10
198 Offline_Uncorrectable   0x0010   100   100   000    Old_age   Offline      -       0

Error 62 occurred at disk power-on lifetime: 4081 hours (170 days + 1 hours)
  When the command that caused the error occurred, the device was active or idle.

  After command completion occurred, registers were:
  ER ST SC SN CL CH DH
  -- -- -- -- -- -- --
  40 53 00 ff ff ff 0f  Error: UNC at LBA = 0x0fffffff = 268435455

@Steve Should SpinRite maybe use the highest reported value between those 2 attributes?

I don't know if Level 5 will fix these uncorrectable sectors when Level 3 didn't, but it might be worth trying. It will take several days to do a full Level 5 scan though.

Thanks for the information, I am going to just let it run a level 5 and see what it does.

This drive does seem to get extremely hot which is not a great indication, but I will let you know results in like 81 hours...

Oh, I missed the temperature. Yeah, 48C is pretty hot. Do you have a fan you can point at it?
