I bought a new 10TB WD Elements hard drive from Amazon. It is quite a loud drive so I decided to run testing on it before use. I use WD Lifeguard in Windows
Short test passes no problem.
Extended test always fails citing “too many bad sectors”
I have also tested it on a MacBook using DriveDX which passes extended testing no problem, no bad sectors.
I then re-tested with WD lifeguard and it still says too many bad sectors after around 5 mins of extended testing.
Which should I believe?
