Which external hard drive will let me to stream music and videos on my Xbox 360

Hello everyone, My friend has a one terabyte extertal hard drive that allowed me to listen to his music and watch his videos through my Xbox 360 via a 2.0 USB. I recently purchased a SeaGate: AgentGo and my Xbox 360 was unable to read the external hard drive. (it shows up as a portable device if there is one plugged in the Xbox 360.)

So I need to know which external hard drives (brand and/or model) will let me stream my media on my Xbox 360, if any of you KNOW which external HD will work by experience PLEASE let me know.

I am having a very difficult time finding out elsewhere on the internet so your help will be GREATLY appreciated. Thank you all for helping me out.

Hey i got a mybook and it works fine, i got some movies and a couple tv shows that i downloaded on it. The only thing that i hate and that i havent figured out yet is that in order to watch them i have to be signed in and connected to the internet.
