if you rely on common knowledge to get you through then you deserve all you get. There are tons of ways to wipe a drive and almost as many ways to create a fat32 partition, assuming you have access to either a windows floppy, the internet, or a running copy of windows.
My point is, why would you ever want to switch back to windows? i say all the better that it was hard to switch back, although that's another thing that's Microsoft's fault.
