4tb red drive is failing

Hi this my first post and hope it’s in the correct place?
I have just noticed that my nas drive has one drive failing, I bought two of them in March 2017 but did not register it with wd and amazon only gives one year warranty. Is there any way to sort it with out buying a new one in any ones Experience?
My second big consent that as they have both been running together as a raid set up does this mean my other one is due to fail as well:(
Thanks in advance
