Hello, I have this drive for about 7 month and it was working fine.
Few days ago when I turned on my PC it stopped working.
BIOS does not see it at all, Windows 10 sees it as unknown device.
I checked in Disk Management and it wants it to initialize but when I want to do it there is an error…
I tried to change SATA cables and ports, still the same.
Go here
(https://support.wdc.com/product.aspx?ID=606&lang=en#WD_downloads)
Get the Diagnostic software and install it.
See if the WD software can find the drive.
Run the long test on the drive if it does see it.
Make a note of the error it finds or what it reports as the problem.
Then go here

See if it is still in warranty and if so RMA it.
