I purchased the 10-Port hub on Amazon last fall, mostly due to the rave reviews. Recently I have been having several issues with it. I have (2) 3 TB Western Digital drives connected to the hub, as well as a printer and an auxiliary 1TB Western Digital drive that I use to backup my hard drive on. All of this goes to a Macbook Pro running Snow Leopard 10.6.6. I will frequently receive the message that all of my disks have been disconnected and that I didn’t disconnect them properly. Sometimes several times in the span of a couple minutes. Also, there are sometimes problems restarting the computer and it often times will hang up due to the drives. Not sure if that part is the Hubs fault or not, but the constant disconnecting of the drives is rather annoying.
