We have a 360 S with 4GB. We bought an internal 250 GB drive. We already have saved game data on the current 4GB drive. When we install the 250 GB, will we lose it all, will it give us an option to transfer it, or do we need to buy a transfer cable or USB storage device. If USB, does it have to be an XBOX USB or just a regular computer one?
Trying not to make the kids mad if we accidentally lose all saved data!
