That kind of noise usually indicates the HDD is failing. Get another HDD and clone the scratching one to it before catastrophic failure. You can keep the scratchy one for storing stuff you don't really care about until it fails, then use the WDC website to RMA and get a replacement - your scratchy HDD should have a 3-year warranty from your date of purchase - you will have to pay for shipping to WDC.
