Where Can I exactly find the external HD?

Sorry everyone. A newbe question:

In the apple tv menu, where can I actually find the external HD i just plugged in?
Thank you

ps. Is it also possible to install OS x on the apple tv?

There are many places actuallly but you can follow:

Files > Movies > ‘Your external HD’

This will only work if you have usb enabled.

Thank you. But if I install patch 3.2, usb is enable right?
Without any other procedure I shall be able to see my external HD in Files > Movies > “your external HD” ?

thank u again
