Is there a hard drive problem?

I've been having issues with my iPod for a long time now. I just got this for the last Christmas that passed (so, 2014!) I used it for a while, but it stopped working around May or June of this year. iTunes told me that it was corrupted, and I was devastated, because relied on my iPod pretty heavily.

Maybe about a month ago, I was able to get it to connect to iTunes and do its thing, but when I tried to add more music to it again at a later time, it stopped working again.

I think there is a hard drive issue, b/c there is a loud whirring noise and little clicks, and hard drive seems to be where all the websites are pointing to. I just want my iPod back and need some guidance.
