Hi keebo,

I think it's a power supply issue, Mac's suggestion is a possibility as well. If you have a bunch of other USB devices, and you're using ports on the front of your computer or a hub, you could see symptoms like that. To confirm if it's a power issue, you could plug it in directly into a port on the back of your computer or temporarily remove some of the other devices. Your self-powered USB hub would solve this. The 1.5 TB drives aren't USB powered so you wouldn't see the same issue with those.
