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.
I agree with @Vegan, if the drive is okay then this should not be showing any bad sectors, in any diagnostic tool. If the drive is under warranty then try to get the replacement of the drive or else try the below methods to fix the bad sectors of the drive:
