Upgrading external hard drive

i currently have only a 300 GIG external drive hooked up to my atv.
i’m thinking of upgrading to a TB. whats the easiest way? Do I have to resync everything to the new drive, or is there a way to connect the drive to my PC and copy everything over to it?

Assuming all your purchased content has been synced back to iTunes, the most straightforward way would be to resync everything to the new drive.

  1. Switch to internal storage via Maintenance → Settings.
  2. Connect new drive.
  3. Switch to external storage through same menu.
