and when you reboot all drives show up without any problems ?
also when your mini goes to sleep do you ever get the error message "drive did not eject properly"
?
one last thing about the Port 1 provides 10W"
can you still use port 1 for external drives or is that port only for charging ipads/iphones when the computer is off
Port 1 you can use for anything (hard drives etc). It works as a charger even if the mini is turned off (as long as the hub is obviously powered). I ran a 3TB drive for Time Machine on it for a while. No problems.
When I reboot, all drives show up no problems (for the ones I have run), but, some drives remain powered 'on' when I shut down the mini. This is not a problem for me as I run my mini 24/7.
It is not a fault with the hub. It's more to do with the type of drive I find. Some powered drives such as Seagate Barracudas (which have no on/off switch) will still have their capacity lights showing. In other words the hub does not completely sleep even if the mini is shut down. Bus powered devices do shut down completely I have found. It has not been an issue for me though.
I have never tested it on sleep (and can't at the moment because I am running something) because it is running 24/7. There are certainly no issues with shutdown or startup for me though.
Also note: the Apple Super Drive will not work on a hub (although some have suggested it does on some older USB2.0 hubs). It won't work on this hub.
I think if you want to run multiple drives of a hub and have the mini sleep and wake often then you will run the risk of some issues no matter what hub you use. For me, the 10 or so peripherals I have run have been fine for shut/start but there are a lot of USB3.0 controllers out there that sleep/wake differently. Also, some controllers have built in sleep modes. All I am saying is there are a million possibilities.
