The PSU is a fairly reliable HEC Zephyr 750, so it looks to be powering the drives fine. However, the only thing common to all drives, aside from the controller, is power. If it is a power issue, then it has to be a dirty power or partial power that allows the disk to spin, but may be preventing it from properly powering all its circuitry to respond to the drive initialization.
According to http://www.badcaps.net/forum/printthread.php?t=6390 that HEC is somewhat unusual, with 4 12V rails, besides using Teapo caps. I don't understand how multiple rails differs from all 12V power on one rail, but it wouldn't surprise me in a more complicated than usual design that some sort of fallible synchronization mechanism is built in or that only one rail is supplying the power reaching the controller, so I'd definitely not rule out PS trouble if it's 7 years old. Newer power supplies seem to have mostly switched back to using only a single 12V rail, or at most two. No idea whether this would be about cost rather than functional efficacy or reliability. -- "The wise are known for their understanding, and pleasant words are persuasive."
