Just purchased a new WD REd 4TB drive and ran it through 2 preclears.  Does the drive look bad?  Seems like a lot of blocks pending reallocation

 

== WDCWD40EFRX-68WT0N0  WD-WCC4E3AN2XYU

== Disk /dev/sdb has been successfully precleared

== with a starting sector of 1

============================================================================

** Changed attributes in files: /tmp/smart_start_sdb  /tmp/smart_finish_sdb

                ATTRIBUTE  NEW_VAL OLD_VAL FAILURE_THRESHOLD STATUS      RAW_VALUE

      Raw_Read_Error_Rate =  198    100          51        In_the_past 4043

    Reallocated_Sector_Ct =  157    200          140        near_thresh 1289

      Temperature_Celsius =  119    121            0        ok          33

  Reallocated_Event_Count =  192    200            0        ok          8

No SMART attributes are FAILING_NOW

 

0 sectors were pending re-allocation before the start of the preclear.

1153 sectors were pending re-allocation after pre-read in cycle 1 of 2.

I think it has to fail WDs tool first before they allow an RMA.  Return if you can. 

 

Once, I accidentally rapped a drive on the table while it was plugged in, and it definitely did not help its health.  In fact, WDs tool couldnt even see it.  Moral of the story is, I need to be more careful.
