The 30 Gb has the OS installed, while the other is reserved for programs and such...
When I want to format the OS Partition again and reinstall WINXP an it....all the libraries and links to the Programs and Applications are truncated...
You will have to reinstall every single program and such...
i suppose if you could figure out what registry stuff each program installs (with some sort of registry monitor perhaps?) you could back that stuff up for later restoring.
