How to Transfer Roster Updates to a Xbox 360 Using a USB Hard Drive

Turn on the Internet-connected Xbox 360 console. If the console has not already received the Spring 2010 update, the system will do so now.

Insert the flash drive into one of the two USB ports on the front of the Xbox 360 console.

Select "System Settings" from the "My Xbox" group of options on the console dashboard.

Select "Memory" from the system settings listed. At the next screen, select "USB Storage Device."

Choose how you want the drive to be formatted by selecting either "Configure Now" or "Customize." Selecting "Configure Now" will automatically format the drive for use with the 360, erasing all data on the drive. Choosing "Customize" will allow you to determine how much memory will be reserved for Xbox use, up to 16 GB total. Confirm your decision, and the console will format the drive. Following the configuration process, the console will test the device to make sure it was successfully formatted. If the device passes, it is ready to transfer content.

From the "System Settings" menu, select "Memory" again. Choose the memory device that contains the content you wish to transfer, such as the main system hard drive.

Select the type of content you wish to copy and transfer from the list of options. For game content such as roster updates, select "Games" from the list.

Select the item you wish to copy to the USB drive for transfer. Game content is located under the name of the game itself.

Choose "Copy" or "Move" for the content you wish to transfer. The console will ask you which drive you wish to copy or move the content onto. Select the USB drive formatted earlier. The content will be transferred onto the USB drive. The drive can now be inserted into another console, and the process repeated, to move the content off the drive for use on the other Xbox 360.
