I originally bought a WD20EARS in December 2011 and it was running decently until around June when I noticed it was running slower than normal. I downloaded and installed the DLGDIAG software and the SMART quick test failed with
Quick Test on drive 2 did not complete! Status code = 07 (Failed read test element), Failure Checkpoint = 97 (Unknown Test) SMART self-test did not complete on drive 2!
So I requested an RMA and got all the data moved to the new drive. I ran the diag on the new drive when it came in and it passed then after a week or two it started doing the same thing as the first, so I ran the diag on it and got the same smart failure message. Opened a new RMA, the newest drive arrived last week and I spent the weekend copying data over and it would not copy faster than 3.0MB/s so it took all weekend to do the copying, it did seem like it was the old drive causing it to go slow as the newest drive passed diags and I could copy to it faster from another drive in my PC. So now I have removed the old drive and have just my primary drive, and this newest replacement in it. Now I’m getting the same error as I have on the previous 2 drives and access to the drive is slow.
It just seems odd that I’d have 3 drives fail with the exact same issue and symptoms within such a short time frame. Any suggestions?
