I recently built the computer in my sig but ever since I first started using the HD a few weeks ago, it sounds like the HDs from the old Compaq/HP computer that make noises everytime it accesses the drive. The drive works perfectly but it annoys me that I have to hear it access the drive. Is this normal or can I get an exchange for it? How would I classify the problem? The drive is a WD 74GB Raptor.
