Hey, the last time my Helios4's PSU blew I suspect was due to a power overload, with the PSU not being able to deal with all 4 HDDs doing active work (this also killed one of the HDDs in my array). Based on the system log, it looked like the system was doing a regular integrity checks on all 4 HDDs at once (!). I would like to either disable the integrity check altogether, or more ideally, spread it out. I have two RAID-1 arrays, and there is no reason for all four drives to be checked simultaneously. For example, I can check one of the arrays (two HDDs) and then once that is done, the second array (the other two HDDs) after. Does anyone know where the code/script for the integrity check lives? The closest I found was /etc/cron.daily/mdadm which runs mdadm --monitor --scan --oneshot but from the manpage description it is unclear to me whether that is superficial check or that may actually invoke a deep and lengthy integrity check.

I have the exact same problem. The board does not recognize any HDDs, attempting to boot it solely off SD card (with HDDs and fans disconnected) one can clearly hear a chirping sound coming from the board itself. Can anyone recommend a good replacement AC/DC adapter?
