Round 2 at the bottom.  Are the attributes useful to post?

 

New disk.  I don't think I've had pending sectors go up before.  Any recommendations?

I have only found 4 SMART reports from either 8TB or 10TB Ironwolfs with enough working hours to get stable normalized values for (1)RRER (7)SER and (195)HER. It is still an small sample to make general assumptions but the data seem to support the hypothesis I posted here that SMART values for the Seagate 8TB drive ST8000DM002 (heavily tested by BackBlaze) could be used as a guide of "normal SMART values" for the new 8TB and 10TB Ironwolf series.

 

The behaviour of Seek Error Rate seems typical for a Seagate drive:  A worst value of 60 and a normalized value somewhere between 70 and 85. The Read Raw Error Rate also seem normal compared to the data I have so far.

 

The (195) Hardware_ECC_recovered value is the one that I really want to figure out before I pull the trigger on the ironwolfs. Those values so close to zero worried me. However they seem to be normal for the Seagate ST8000DM002 and for the Ironwolfs I have seen so far.

Sorry  for my late reply. Thank you very much!

My fourth IronWolf is preclearing now. This time I'm using the preclear plugin. Will post results once I get them

 

Here are the SMART reports of my three drives after using them for a few months. They have been on 24/7 and with the purchase of my third drive the setup is Raid5. I hope this is not considered as offtopic.

I just tested this script using unRAID version 6.5.0 and it completed without error.  I collected the report on this preclear operation using   grep   and it looked identical to those reports which I had previously generated by the same command.  This script was version 1.15 and I modified it per Joe L.'s instructions to work with version 6.2.X and later.  See here for details:

Hi unRAID fans!  new disk that I had laying around. Is it ok for the server?  

 

With a no pending sectors at start and over 100 pending sectors by the end of the test, I would never consider using this drive in any server of mine.  (Some folks may tell you to run another preclear cycle and see if they clear up, but I would be more worried that this disk is already in a failure mode.  Remember, you have to be able to read every sector on every disk if you are going to rebuild a failed drive....)   With only 6500 hours on it, it may be eligible for a warranty return.

Thank you Frank1940 I will see about the warranty. I appreciate the help.

Earlier this month I bought a WL 6TB drive that cleared fine, so I bought a second, but it looks like this one is failing. I'm using the same power/sata ports/cables as i used for the first drive. Any reason to try something different, or should I send this one back?

 

I ran the clear script twice - first post-read failed at about 86%, but 2nd seems to have failed immediately.

I'm somewhat new to Unraid and I just built this server about 3 months ago. I got a 'new' 6tb drive and cable installed and everything was going great, then I got an error. I've searched the forums and reddit but not really finding an answer. Can I just restart the read validation since the write is already done?

I'm somewhat new to Unraid and I just built this server about 3 months ago. I got a 'new' 6tb drive and cable installed and everything was going great, then I got an error. I've searched the forums and reddit but not really finding an answer. Can I just restart the read validation since the write is already done?

I an not an expert... but when your preclear states that it failed on 2.1 tb of data... and this is a 8tb drive... kinda makes me wonder... are you 100% sure you cleared the correct drive?

 

else... I would return the drive...

 

no reason to keep/troubleshoot a drive that is acting funny from the start...
