Question about Kingston XS2000

What OS do you have? Windows or Mac? I would check the SSD first. Depending on the OS, there are several tools.
You can also try copying files with the terminal, sometimes it still works.

Warranty case. The disc I have also had a total failure. No more access and was no longer recognised correctly. Has been replaced.

It was the same for me. I was able to return it during the warranty period
