1. No, it is directly plugged into the mac mini.
2. Yes, it uses the provided USB cable.
3. Not usually, but I tested doing so and there is no change in behaviour. The shutdown/restart is always clean, i.e. via the proper OSX restart.
4. No, the drives are not visible via Disk Utility either.

This problem persists as of OSX 12.6. I have 3 of the 4 drive bays filled, with 2 new drives and one older one (different type and capacity). None of the drives mount upon a reboot, until I unplug/re-plug the enclosure. This doesn't happen with the StarTech external drive enclosure I also have, nor ...

Repeating the same words back to me is not a useful explanation. Do you mean you want me to remove the old hard drives and replace them with newly purchased ones? That rather goes against why I bought this unit in the first place. Or do you mean reformat them (again as I've already done that twice) ...

Alright, I removed the OSX RAID functionality and am now using it as 2 independent drives. Problem still occurs.

And now one of my 2 drives isn't appearing.

Unfortunately these articles (and all the others I've found) presume that the device doesn't mount at all. In this case the D4-300 just doesn't mount when I reboot into OSX. If I unplug/replug the device, it is recognized immediately and everything is fine. I've even tried resetting the USB bus via ...
