hard drive issues

[nerdrage3185]

I am having an issue with hard drives failing. I have gone through 3 hard drives, boot drives in a month. The first two I had bought in 2010 so I figured they were just old. The first one started clicking really bad and an error message kept coming up saying something like "Bad Drive back up data" or something similar. So I got one of my other drives which I was using to store movies on for the past couple of years and a week later same thing. So I used a hard drive i had bought and been using for 2 months and it keeps clicking and freezing up but I am not getting the error message. Its like it is constantly scanning. It is only 16 % fragmented and I have the partition split so I can store my frequently accessed movies on the bigger partition. Anyone else had a similar problem or know what is going on. Posting a picture should I put all my movies on the second disk drive and just do a single partition on my main drive.
