Benefits of 64-bit Windows? (and external HDD questions)

[dbot]

You can always by an IDE to USB adapter for $13 and use your existing hard drive as your external hard drive. That would save you the step of copying files, and you will still have a working installation of Windows if things go badly for you. I am not sure what type of interface your existing drive has, but they make adapters for all of them.
