Help with preclear results

[wsume99]

Last night I installed my new WD Black 1TB drive (WD1001FALS) and ran a preclear on it overnight.  My syslog file is attached.  Two questions...

 

1) It looks to me like the smrtcrtl is not installed.  I'm running unRAID Basic v4.5.6.  I'll have to read more about installing that.

 

2) Can anyone tell me what the smart report is telling me WRT Raw_Read_Error_Rate and UDMA_CRC_Error_Count and if it's anything to be worried about.

 

I'm guessing I'll be told to fix #1 then rerun preclear a few times but wanted to get some input from the experts here.

It is installed... Its output is in your syslog.  It has been a standard part of unRAID for a very long time.

Nothing to worry about at all.  The factory initialized values for those two parameters seems to be 253, the "starting" value once the drive gets some use seems to be 200.  The failure threshold is nowhere close.

What makes you think smartctl is not installed?  (it is, and you posted its output as sent to the system log)

 

Your drive is perfectly fine, you just need to learn a bit more about how to read a smart report.  There is a huge thread with requests similar to yours and the descriptions of how to interpret the results.  Start there for more info.

I misinterpreted what you meant in the 2nd edit of your first post in this thread.  That is why I thought that smartctl wasn't working properly because I thought the version I am using would be affected.  I think I found the thread that discusses the preclear SMART reports you were talking about here.

Wow.  I read all 16 pages of the thread that is used for posting preclear results.  VERY HELPFUL!  Yep my drive is fine, although I'm going to run preclear again just to be safe.

 

I'm wondering, do you run smartctl regularly (monthly) and log the reports to track drive health over time?
