Hi everyone, hope all is well. Lately when I've been on the computer I've found a strange noise to be coming from my hard drives, not sure which one at the moment. I have a WD red 2TB, and two WD blacks; 1TB and 5TB. I was wondering if perhaps the noise may be from the hard drive spinning up and stopping several times, or if I should be more worried about the clicking noise of death. SMART is showing all drives are in good shape, but is there a specific parameter that I should be looking at which could help determine which drive is more worn down than the others? Many thanks in advance.
