I just added a new hba card the adaptec hba1000 8i8e and connected the 5 internal drives to it. Everything went fine when I added the card, it sees all the drives, everything works as expected. I spin down my hdd after 1 hour of inactivity. The array is 1 parity and 4 hdds. Four of the drives are 16tb exos and 1 is a wd 16tb WDC_WD160EDGZ-11B2DA0. For whatever reason, that drive keeps waking up after being spun down for 5min. In the log I see it's spun down and then 5min later wakes up. There is 0 activity on the server, no dockers are trying to access it.

I see that constantly, today. A few minutes after the drive spins down, it wakes back up. Not sure what the reason for that would be. I have just completed a parity check, there are no errors. All the cables are brand new, so I'm not sure what's causing this thing to constantly wake up. Prior to this I had an m2 to sata adapter where all 5 drives were connected to it in the past year. Never experienced this issue. Any ideas would be welcome.

You are likely to get better informed feedback if you attach your system’s diagnostics zip file to your next post in this thread. It is always a good idea when asking questions to supply your diagnostics so we can see details of your system, how you have things configured, and the current syslog.

New cables doesn't mean good cables. Went back and swapped 1 of the breakout ssf 8643 to sata cables that was connecting the drive. It looks like the cable was faulty. Since the change, no more issues.
