I purchased a Western Digital Elements 4 TB portable hard drive. It's only 4 months old and only has about 300 GB's on it. Yesterday it started making loud clicking sounds. You can feel them if you put your hand on top. I safely removed it and tried again, but still the same loud clicking sounds. I always thought there was a SSD inside it because it's so small, but SSD's don't make clicking sounds. Any advice would be appreciated. Thank You.
