WD Caviar Blue 1TB makes strange noise

Hey, everyone. I been having a problem with one of my HDD, it started to make a strange sound. I tried to record it but the recorder can’t ‘hear’ it. It is some sort of scratching noise (like little sparks) I dont know how to properly descrive it. It is not reading / writing noises or spinning up. The only think I know it isnt normal.
It has arround 3 or 4 yeears this HDD

If someone has an idea of whats happenning or anything would be great! Thanks!
