Instead of having a hard drive on your Microsoft Xbox 360 you can instead use any USB hard drive. The limitation is the fact that you can only format 16GB of any USB drive to work with the Xbox 360 so unless you want multiple partitions on the USB drive I would actually just purchase a USB flash drive with a maximum of 16GB of usable space. To use the USB flash drive with your Xbox 360 you have to first format the drive which is explained in detail below.

Below is information on how to install AVIcodec and how to analyze video files once AVIcodec is installed.
