What's a good Windows partition scheme? [View All]

[IronLionZion]

I'm thinking about doing a clean install of XP SP2 on a 120 GB drive. I figure keeping 20GB for OS and programs, and 100GB for data would be good. That way I can reinstall win-blows without losing the data. And I would have to do a clean install of the programs which would avoid registry issues.

What do you think?

Or should I keep a partition just for windows and keep programs on the data partition, with the possibility of registry issues. Or should I have 3 partitions: Windows, programs, and data? Or something else?

What do you all suggest?

I like programs. When some new open source software comes out I like to try it. And some games too. I'm always installing and uninstalling stuff.

Do you think it's worthwhile to have a swap area too?
