It’s been roughly 20 years now but my employer at the time had a number of servers that started having odd drive failures at similar times. Long story short we eventually discovered that it was the power supplies that were starting to fail.
These servers had something like 6 hard drives in them, and while troubleshooting we started seeing a pattern where any 5 would work, but as soon as the 6th was reconnected then drives would randomly fail. We eventually replaced the power supply and all 6 drives were happy again.
