So here's an interesting story, maybe I'll get some feedback, but mostly I expect this to be an FYI for anyone else looking at these drives. I have a Norco RPC-4224 case w/ hotswap drive cages. The backplane power is fed by Molex connections having 5v and 12v lines so I assumed there would be no issues. In early November I bought a pair of 10TB Easystores that I shucked and stuffed into my server. They work just fine and I had no reason to expect issues on future drive purchases. I just bought another pair of Easystore 10TB drives and shucked them. Interestingly the manufacture date is 2 months before my other drives. They refuse to spin up unless they have the 3v pin isolated. All the pertinent #s between the drives are identical firmware, model #, P/N #, everything. I was expecting that this 3.3v issue was handled by the firmware. Am I wrong or are they abusing the firmware #s by having functionally different FW? Any chance someone knows a method to pull firmware from one drive and put it on another? Thanks!
