Hey guys, I recently installed a Western Digital Caviar Black 1TB SATA3 6GB/S 7200RPM 64MB Cache HDD in a Coolermaster CM 690 II Advanced. I installed Windows 7 without any probs and everything is working fine. However, the HDD is making a loud grinding noise whenever it's in use and I'm not sure why. Is there a chance it might be defective or maybe I should change the drive bay ?
