Hi,
One small comment, if the original source is large, like in AIO disks (over 4gb), then you better format fs=NTFS to allow larger than 4gb files.

Thanks for the great tutorial. It worked just like you said except I had to select drive 2. I have it on a Memorex 4 GB USB 2.0 and the files load 3 times faster than they ever did off of the CD Installation Disk.
I almost never post replies on sites. This was a very well explained article and the screenshot is awesome. Thank you for saving me a lot of time. Much appreciated.
