I've experienced the same issue across 14 different WD red drives, mixed 10/8tb and helium/air filled. Whenever the pair in my Synology do it, the sound resonates so loud you can hear it across the house. I've tried everything to get them to stop, but sometimes they still make the noise for 30+ minutes at a time.

I initially thought part of the issue might be due to the drives being mounted directly to the case so I bought a set of anti-vibration rubber drive mounts, but it didn't help at all.

Yeah I thought it might be resonance between two drives moving similarly in a mirrored pair, so swapped the drive order around, but that made no difference either.

I've used primarily WD drives for years but I think my next pair will be from a different manufacturer and will likely replace these golds, which can be relegated to a second machine in my shed where I can't hear them.
