But if you assume the failure rate of any HDD is approximately same. Then with given conditions above: Your 4 HDD Raid0 arrays possibility of failure is 4 times more than one HDD. I think you mix up Raid0 with other modes... Just to note it.
I mixed nothing. I refer to when multiple HDD run together to act as one. Yes, when 1 fails they all go down... I guess I wasn't clear. Yeah IF the fail rates were the same you'd be right, 4x the possible fail rate... but the rates aren't the same. The fail rates of a conventional spinning HDD go up exponentially with storage capacity. This is why a raid0 setup is now more reliable than a single drive when total capacities are matched. Again though, nothing beats a solidstate, and since these are getting larger and cheaper my point will soon be moot.

So I assume this is the problem, but how do I fix it? Can I even fix it? My HD is pretty new (some months old) and I've never faced anything like that.

Another screenshot of when I'm trying to use the Check Filesystem button -

I assume this error is also the reason why I can't run any self-tests for the HD?

Would really appreciate your help, I still have my warranty so let me know if I should ask for a new one

Thanks in advance.
Assuming you don't have some environmental issue like accidentally providing 12 volts to the top of the hard drive, or a mouse died inside your computer...

Your drive might be fully recoverable with a long format, secure erase or the like. It may also be recoverable with Spinrite (if you can't erase because you have nowhere to backup your data). If you see the error again after erasing the disk, then RMA it. One thing is for sure, the drive will never be the same.
