Bests & Worsts Reviews from Amazon

Just got it this afternoon. I have learned from bad experience that it is critical to test hard drives when you get them. I ran the WD Diagnostics and it hangs at 10%. I then ran WD Lifeguard short test, and it failed that test, with error Checkpoint =97 did not complete smart test. However, the smart test by itself is OK. My computer also rebooted doing these tests. Will do some further tests and I contacted WD, but looks like this is going back.
