Error in NAS with WD20EARX

I have used two WD20EARX (2.0TB) in a NasDuo for abot four weeks (six hours daily working) whwn I receive a message that one drive was wrong. I replace this wrong drive by another WD 2.0 TB HDD. 

I have checked the defekt drive with Data Lifeguard Diagnostic for Windows. First the quick test fails, the extended tests runs with errors. At the end the programm offer to repair what was successful (read error was fixed). After this also the quick test was successful.

Now I have checked the drive with DH DriveInfo 4.0.593. This programm reports under Health status: 100% Dangerous. I attach the report below.

For my recertifoied drive I have a rest warranty of 39 days. What shall I do. Is the status of the drive a reason to complain for a warranty excange?

Hello,

I think you should create a RMA and get this drive replaced.

How to get an RMA, (Return Merchandise Authorization) or replace a defective product under warranty
