I would say it's done to find out if the hub is able to power the drive...siafu77 wrote:I haven't tried using the powered hub on the laptop because it works fine through on board USB. I wouldn't think that I needed to run a powered hub off of the laptop if it has no problem powering USB drives. I will try later and report back. I am fine with running it smb right now but I was just wondering.
